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
passed.

This toolchain uses an old gcc 6.2.0 compiler (not even the latest gcc

package. Since newer versions of this toolchain are no longer made
publicly available from Mentor Graphics, our only option is to drop

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".

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.

toolchain which is GCC 4.8 and kernel headers 3.13. Therefore, it is

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.

Some installations mount /tmp with the 'noexec' option, which prevents
running the program generated there to check the kernel headers.
Avoid the problem by generating the program under $(BUILD_DIR), passed
as the first argument to check-kernel-headers.sh.
We could globally export a TMPDIR environment variable with some path
under $(BUILD_DIR) but such solution would be too intrusive, depriving
the user from the freedom to set TMPDIR at his will (or needs).

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
tree possible and available in the same location as the ones known to
Buildroot:

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
case.

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.

commit e0d14fb21b (toolchain-external: drop no longer needed
CC_TARGET_<foo>_ variables) dropped the CC_TARGET_* variables, but missed
one. Fix that.

Since the introduction of the GCC_TARGET_<foo> variables in
arch/arch.mk in commit bd0640a213
("arch: allow GCC target options to be optionally overwritten") and
the removal of the BR2_GCC_TARGET_CPU_REVISION, the CC_TARGET_<foo>_
variables in pkg-toolchain-external.mk map 1:1 with the corresponding
GCC_TARGET_<foo> variables.
So let's drop the CC_TARGET_<foo>_ variables, and use directly the
GCC_TARGET_<foo> ones.

In commit 325bb37942, support for the
Blackfin architecture was removed. This was our only use of
BR2_GCC_TARGET_CPU_REVISION, and since this config option somewhat
complicates the calculation of the --with-cpu/-mcpu option values,
let's drop it.

The BR2_GCC_TARGET_* configuration variables are copied to
corresponding GCC_TARGET_* variables which may then be optionally
modified or overwritten by architecture specific makefiles.
All makefiles must use the new GCC_TARGET_* variables instead
of the BR2_GCC_TARGET_* versions.

The check_musl function currently builds a program and verifies if the
program interpreter starts with /lib/ld-musl. While this works fine
for dynamically linked programs, this obviously doesn't work for a
purely static musl toolchain such as [1].
There is no easy way to identify a toolchain as using the musl C
library. For glibc, dynamic linking is always supported, so we look at
the dynamic linker name. For uClibc, there is a distinctive
uClibc_config.h header file. There is no such distinctive feature in
musl.
We end up resorting to looking for the string MUSL_LOCPATH, which is
used by musl locale_map.c source file. This string has been present in
musl since 2014. It certainly isn't a very stable or convincing
solution to identify the C library as being musl, but it's the best we
could find.
Note that we are sure there is a libc.a file, because the
check_unusable_toolchain function checks that there is a such a file.

There are cases where a downloaded toolchain doesn't have its binaries
placed directly in a "bin" subfolder (where BuildRoot currently looks
for them).
A common example is the official Raspberry Pi Toolchain
(https://github.com/raspberrypi/tools), which has its binaries in
"arm-bcm2708/arm-linux-gnueabihf/bin".
This commit introduces BR2_TOOLCHAIN_EXTERNAL_REL_BIN_PATH that defaults
to "bin" and can be changed as needed.

libatomic, like libgcc_s, is provided by gcc, so there is no reason to
copy it over only for the glibc and uclibc cases, it should also be
copied for the musl case. Without this, a program linked with
libatomic on a musl system will fail to run due to the missing
library.

The upcoming per-package SDK functionality is heavily based on the
fact that HOST_DIR, STAGING_DIR and TARGET_DIR are evaluated during
the configure/build/install steps of the packages. Therefore, any
evaluation-during-assignment using := is going to cause problems, and
need to be turned into evaluation-during-use using =.
This patch fix up one such instance in the external toolchain code.
This change is independent from the per-package SDK functionality, and
could be applied separately.

This merges the next branch accumulated during the 2017.11 release
cycle back into the master branch.
A few conflicts had to be resolved:
- In the DEVELOPERS file, because Fabrice Fontaine was added as a
developer for libupnp in master, and for libupnp18 in
next. Resolution is simple: add him for both.
- linux/Config.in, because we updated the 4.13.x release used by
default in master, while we moved to 4.14 in next. Resolution: use
4.14.
- package/libupnp/libupnp.hash: a hash for the license file was added
in master, while the package was bumped into next. Resolution: keep
the hash for the license file, and keep the hash for the newest
version of libupnp.
- package/linux-headers/Config.in.host: default version of the kernel
headers for 4.13 was bumped to the latest 4.13.x in master, but was
changed to 4.14 in next. Resolution: use 4.14.
- package/samba4/: samba was bumped to 4.6.11 in master for security
reasons, but was bumped to 4.7.3 in next. Resolution: keep 4.7.3.
