then moving BR2_TOOLCHAIN_GCC_AT_LEAST_9 to BR2_TOOLCHAIN_GCC_AT_LEAST_10

Convert BR2_TOOLCHAIN_EXTERNAL_PATH to an absolute path when used.
Otherwise the symbolic links to the external toolchain binaries are
not installed in host/bin when BR2_TOOLCHAIN_EXTERNAL_PATH is relative.
This happens because TOOLCHAIN_EXTERNAL_INSTALL_WRAPPER
changes directory into host/bin to create the symbolic links.
From there the tools are no longer found via the relative path and
a single symbolic link host/bin/$(prefix)-* is created instead.
Although relative paths sounds like something less than ideal to put in
a Buildroot configuration, it's actually rather typical to put the
buildroot sources as a submodule (or subdirectory) of custom sources
(either in a BR2_EXTERNAL or not), in which case the relative path is
well-defined.

In GCC6 the compiler was made smarter to omit the flag
-fdebug-prefix-map from the DWARF DW_AT_producer section[1]. That flag
contains the absolute path '$(BASE_DIR)' which breaks reproducibility.
Prior to GCC6 however, the only way to omit the flag is to use
-gno-record-gcc-switches which omits all flags.

The gdbinit supplied by Buildroot does two things:
A. specify the sysroot where gdb can find shared libraries
B. mark the sysroot as a 'safe path' for its auto-load feature, to make sure
that pretty printers for libstdc++.so are added automatically (see commit
6fb3216a80)
When debugging a core file, and the gdbinit file is specified via '-x'
rather than '-ix', then the order of these settings matters: If you first
set the sysroot, then gdb will immediately start finding the shared
libraries it needs for the core file, detect libstdc++ and its associated
libstdc++-gdb.py file, then give a big warning about safe paths:
warning: File ".../i686-buildroot-linux-gnu/sysroot/lib/libstdc++.so.6.0.24-gdb.py"
auto-loading has been declined by your `auto-load safe-path' set
to "$debugdir:$datadir/auto-load".
To enable execution of this file add
add-auto-load-safe-path .../i686-buildroot-linux-gnu/sysroot/lib/libstdc++.so.6.0.24-gdb.py
line to your configuration file "/home/me/.gdbinit".
To completely disable this security protection add
set auto-load safe-path /
line to your configuration file "/home/me/.gdbinit".
For more information about this security protection see the
"Auto-loading safe path" section in the GDB manual. E.g., run from the shell:
info "(gdb)Auto-loading safe path"
and the pretty printing code is not loaded. This is because the second
line from the gdbinit file was not yet parsed at this point.
By changing the order (first configuring the safe path, then setting the
sysroot), this issue does not appear and everything is as expected.
Note that when '-ix' were used instead of '-x' to pass the gdbinit file to
gdb, then the order would not matter, because the entire gdbinit file would
be parsed before considering the core file.
However, even though the Buildroot manual now suggests '-ix', users may not
have noticed this change and continue to use '-x'.

gdb can automatically load certain files as described in [1]. Such files
could install pretty-printers for complex data structures.
libstdcxx (C++ standard library) provided by gcc, is one example of a
library for which such auto-load file is available. But there are other
examples too, like libglib2.
However, gdb will only auto-load files if the file is located in one of the
locations treated as 'safe'. The Buildroot sysroot is not by default in that
list.
Provide a better debugging experience by adding the sysroot to the 'safe'
list, via the gdbinit file prepared by Buildroot.

gcc installs a libstdcxx-...so-gdb.py file that gdb will load automatically
when it loads libstdcxx.so, via the mechanism described at [1].
However, the auto-load file installed by gcc contains hardcoded paths
referring to the location where the (external) toolchain was built, which
are normally not available.
Fix up the paths in the load file so that the pretty printers can be loaded
automatically.
Note that gdb will only auto-load the file if its location is marked as
'safe'. A subsequent commit will take care of that.
Technically, there could be more than one load file, e.g. in lib and
usr/lib, so fix them all. This was for example observed in
BR2_TOOLCHAIN_EXTERNAL_ARM_AARCH64.
In a very specific case with a local custom toolchain, there were actually
two 'python' directories, which would break the sed command, so arbitrarily
limit to the first one encountered.

While testing Buildroot on a Cortex-A5 that doesn't provide NEON, we
found out that a system generated with the ARM toolchain from Arm
didn't boot. It turns out that this ARM toolchain is built with:
--with-arch=armv7-a --with-fpu=neon --with-float=hard --with-mode=thumb
So, it uses NEON as its FPU, which means it can only work on CPU cores
that have NEON support. This commit adds the appropriate dependency to
the toolchain-external-arm-arm package, and adjusts the Config.in help
text accordingly.
While at it, it also drops the part of the Config.in help text that
says the code is tuned for Cortex-A9, as it is not the case: it was
the case for the Linaro toolchain (built with --with-tune=cortex-a9),
but not for the ARM toolchain, for which no specific --with-tune is

make-4.3 shipped with a backward incompatible change in how sharp signs
are handled in macros. Previously, up to make 4.2, the sharp sign would
always start a comment, unless backslash-escaped, even in a macro or a
fucntion call.
Now, the sharp sign is no longer starting a comment when it appears
inside such a macro or function call. This behaviour was supposed to be
in force since 3.81, but was not; 4.3 fixed the code to match the doc.
As such, use of external toolchains is broken, as we use the sharp sign
in the copy_toolchain_sysroot macro, in shell variable expansion to
strip off any leading /: ${target\#/}.
Fix that by applying the workaround suggested in the release annoucement
[0], by using a variable to hold a sharp sign.

The external toolchain configure step calls the
check_kernel_headers_version make function to compare the kernel
headers version declared in the configuration with the actual kernel
headers of the toolchain.
This function takes 4 arguments, but due to a missing comma what
should be the first two arguments are both passed into the first
argument. Due to this, when check_kernel_headers_version does:
if ! support/scripts/check-kernel-headers.sh $(1) $(2) $(3) \
$(if $(BR2_TOOLCHAIN_HEADERS_LATEST),$(4),strict); \
Then:
$(1) contains "$(BUILD_DIR) $$(call toolchain_find_sysroot,$$(TOOLCHAIN_EXTERNAL_CC))"
$(2) contains "$$(call qstrip,$$(BR2_TOOLCHAIN_HEADERS_AT_LEAST))"
$(3) contains "$$(if $$(BR2_TOOLCHAIN_EXTERNAL_CUSTOM),loose,strict))"
So from the point of view of check-kernel-headers.sh, it already has
four arguments, and therefore the additional argument passed by:
$(if $(BR2_TOOLCHAIN_HEADERS_LATEST),$(4),strict); \
is ignored, defeating the $(BR2_TOOLCHAIN_HEADERS_LATEST) test.
The practical consequence is that a toolchain that has 5.4 kernel
headers but declared as using 5.3 kernel headers does not abort the
build, because the check is considered "loose" while it should be
"strict".

This will allow toolchain to indicate if they support
-fstack-protector-strong or not.
Whenever the gcc version is >= 4.9, we always have SSP_STRONG support
if we have SSP support. However, some toolchains older than gcc 4.9
might have backported SSP_STRONG support, which is why we cannot rely
just on BR2_TOOLCHAIN_GCC_AT_LEAST_4_9.
Having this "default" value allows to avoid adding a "select
BR2_TOOLCHAIN_HAS_SSP_STRONG" in the internal toolchain logic plus in
almost external toolchains. But it allows custom external toolchains
that are pre-4.9 to potentially declare that they support strong SSP.

When Buildroot is released, it knows up to a certain kernel header
version, and no later. However, it is possible that an external
toolchain will be used, that uses headers newer than the latest version
Buildroot knows about.
This may also happen when testing a development, an rc-class, or a newly
released kernel, either in an external toolchain, or with an internal
toolchain with custom headers (same-as-kernel, custom version, custom
git, custom tarball).
In the current state, Buildroot would refuse to use such toolchains,
because the test is for strict equality.
We'd like to make that situation possible, but we also want the user not
to be lenient at the same time, and select the right headers version
when it is known.
So, we add a new Kconfig blind option that the latest kernel headers
version selects. This options is then used to decide whether we do a
strict or loose check of the kernel headers.

In commit 6136765b23 ("toolchain:
generate check-headers program under $(BUILD_DIR)"), the
check_kernel_headers_version function was simplified to not check the
return value of the check-kernel-headers.sh script, assuming that
"make" does bail out on the first failing command.
However, check_kernel_headers_version when used in $(2)_CONFIGURE_CMDS
from pkg-toolchain-external.mk, is called in a sequence of commands,
where the return value of each command is not checked. Therefore, a
failure of check-kernel-headers.sh no longer aborts the build.
Since all other macros are using this principle of calling "exit 1",
we revert back to the same for check_kernel_headers_version, as it was
done prior to 6136765b23.

This patch extends the "copy extra GCC libraries to target" feature to
also work for internal toolchains. The variable has been renamed to be
BR2_TOOLCHAIN_EXTRA_LIBS and the configuration option moved under the
generic toolchain package. For external toolchains, the step that does
the copy is still in the copy_toolchain_lib_root() helper which copies
from the sysroot to the target. For the internal toolchain, the host
gcc-final package does a post install hook to copy the libraries from
the toolchain build folders to both the sysroot and target(!static).
Examples where this can be useful is for adding debug libraries to the
target like the GCC libsanitizer (libasan/liblsan/...).

Commit 32bec8ee2f
("toolchain-external: copy ld*.so* for all C libraries") changed (among
other things) the glob pattern to catch the dynamic loader from
ld*.so.*
to
ld*.so*
thus now matching files like 'ld-2.20.so' in addition to files like
'ld.so.1'.
However, there is no apparent reason why that change was made. It is
not explicitly mentioned in the commit message as to why that would be
needed, nor is clear based on the rest of the changes in that
commit. But it turns out that it causes too many files to be copied
with some toolchains.
In most toolchains, the structure looks like this:
-rwxr-xr-x 1 tdescham tdescham 834364 Feb 16 21:23 output/target/lib/ld-2.16.so
lrwxrwxrwx 1 tdescham tdescham 10 Feb 16 21:23 output/target/lib/ld.so.1 -> ld-2.16.so
So, a symlink 'ld.so.1' which points to another file. Applications
would have 'ld.so.1' (the link) encoded as program interpreter
(readelf -l <program>, see INTERP entry)
The patterns like 'ld*.so*' are passed as argument to
copy_toolchain_lib_root which is defined in toolchain/helpers.mk.
This macro copy_toolchain_lib_root will find all files/links matching
the pattern. If a match is a regular file, it is simply copied. If it
is a symbolic link, the link is copied and then the logic is
recursively repeated on the link destination. That destination could
either again be a link or a regular file. In the first case we recurse
again, in the latter we stop and continue with the next match of the
pattern.
The problem this patch is solving is when a toolchain does not have
this structure with a link and a real file, but rather two actual
files:
-rwxr-xr-x 1 tdescham tdescham 170892 Feb 16 21:55 output/target/lib/ld-2.20.so
-rwxr-xr-x 1 tdescham tdescham 170892 Feb 16 21:55 output/target/lib/ld.so.1
In this case the pattern 'ld*.so*' would find two regular file matches
and copy both. On the other hand, the pattern 'ld*.so.*' would only
find the 'ld.so.1' file and copy just that. This saves about 170K in
rootfs size.
Closer inspection reveals that this particular toolchain has more such
dedoubled symbolic links, e.g. the standard pattern of
'usr/lib/libfoo.so -> libfoo.so.1 -> libfoo.so.1.0.2' is not present,
and each of these three components are real files. In any case, it is
obvious that the toolchain itself is 'broken'.
That being said, because we have the logic that recursively resolves
symbolic links, TOOLCHAIN_EXTERNAL_LIBS really only needs to contain
the "initial" name of the library to be copied.
Therefore, revert the glob pattern back to what it was.

In Buildroot, the internal toolchain backend uses the SSP support from
the C library, not that of gcc.
Some external toolchains come with SSP suport in gcc, which is
implemented in libssp.so, rather than in the C library.
When a toolchain even has both, it is up to the compiler to decide
whether it will link to libssp or use the support from the C library.
However, in the latter case, a (incorrectly written) package may decide
to explicitly link with libssp.so when it is available (even though the
compiler may have decided otherwise if left by itself). This is the case
for example with sox, which results in runtime failures, such as:
$ sox
sox: error while loading shared libraries: libssp.so.0: cannot open
shared object file: No such file or directory
Even if sox is wrong in doing so, the case for libssp-only toolchains is
still valid, and we must copy it as we copy other libs.

We could globally export a TMPDIR environment variable with some path

Since we have a choice for the pre-configured pre-built toolchains,
there is no possbility for a br2-external to provide its own. The
only solution so far for defconfigs in br2-external trees is to use
BR2_TOOLCHAIN_EXTERNAL_CUSTOM and define all the bits by itself...
This is not so convemient, so offer a way for br2-external trees to
provide such pre-configured toolchains.
To allow for this, we now scan each br2-external tree and look for a
specific file, provides.toolchains.in. We generate a kconfig file that
sources each such file, and that generated file is sourced from within
the toolchain choice, thus making the toolchains from a br2-external

Some toolchain vendors may have backported those options to older gcc
versions, and we have no way to know, so we have to check that the
user's selection is acceptable.
Extend the macro that currently checks for SSP in the toolchain, with
a new test that the actual SSP option is recognised and accepted.
Note that the SSP option is either totaly empty, or an already-quoted
string, so we can safely and easily assign it to a shell variable to
test and use it.
Note that we do not introduce BR2_TOOLCHAIN_HAS_SSP_STRONG, because:
- our internal toolchain infra only supports gcc >= 4.9, so it has
SSP strong;
- of the external pre-built toolchains, only the codesourcery-arm
one has a gcc-4.8 which lacks SSP strong, all the others have a
gcc >= 4.9;
- we'd still have to do the actual check for custom external
toolchains anyway.
So, we're not adding BR2_TOOLCHAIN_HAS_SSP_STRONG just for a single

The custom external toolchain logic asks the user to specify which gcc
version is provided by the toolchain. The list of gcc versions given
by Buildroot is restricted depending on the selected CPU architecture
using the BR2_ARCH_NEEDS_GCC_AT_LEAST_xyz config options.
However, these config options generally indicate in which upstream gcc
version the support for the selected architecture was introduced. But
in practice, it is possible that an external toolchain uses some
non-upstream gcc code, providing support for a CPU architecture before
it was merged in upstream gcc.
A specific example is that there are pre-built external toolchains for
the C-SKY CPU architecture that are based on gcc 6.x, even if the
support for it was only added in upstream gcc 9.x.
Due to the BR2_ARCH_NEEDS_GCC_AT_LEAST_xyz options, only gcc >= 9.x
can be selected for C-SKY, preventing the use of such a custom
toolchain.
In addition, those dependencies are in fact not really needed:
Buildroot will check that the gcc version provided matches what the
user declared in the configuration. And if the gcc provided by the
toolchain does support that CPU architecture, then well, so be it,
there's no need to restrict the gcc version selected.
So we simply get rid of these dependencies on
BR2_ARCH_NEEDS_GCC_AT_LEAST_xyz, and also don't use them anymore to
chose a default value for the gcc version.

Error: operation combines symbols in different segments
The following defconfig allows to reproduce the issue:
BR2_microblazeel=y
BR2_OPTIMIZE_2=y
BR2_KERNEL_HEADERS_5_0=y
BR2_GCC_VERSION_7_X=y
BR2_PACKAGE_FXLOAD=y
The gcc bug was reported at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63261 and is fixed as of
gcc 8.x.

GCC fails building the haproxy package for the Microblaze architecture:
http://autobuild.buildroot.org/results/64706f96db793777de9d3ec63b0a47d776cf33fd/
The gcc bug was originally reported gpsd:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90620
This gcc bug no longer appeared with gcc 8.x but reappeared in gcc
9.x, so we introduce a config symbol so that packages can work it
around by disabling optimization.

This external toolchain is pre-built for x86, so it can only work on
x86 and x86-64, and for the latter, the ia32 libraries are necessary.

Gcc bug 85180 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180) has
been fixed on Gcc version >= 8.x, so this commit adjusts the
BR2_TOOLCHAIN_HAS_GCC_BUG_85180 option to no longer be true when the
gcc version is >= 8.x.

[Thomas:
- rename .mk and .hash files to carry the proper package name
- fix <pkg>_SITE variable, which was incorrect
- add prompt in Config.in
- add missing include of Config.in in toolchain/toolchain-external/Config.in
- add missing selects for RPC and SSP, since the toolchain supports
both
- drop BR2_TOOLCHAIN_EXTERNAL_URL option, the toolchain URL is
provided by the .mk file]
