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 23c0e97b29 (toolchain-external: anchor sysroot regex with /)
tried to make the find-sysroot work more consistently, especially for
toolchains where the C library is located in a sub-directory, like the
"Realtek mips toolchain".
After that patch, the '/' that was trailing in the returned path got
removed now. This in turn breaks the Codesourcery toolchain.
We fix that by appending the now-missing trailing '/'.

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.

When an architecture expresses a requirement on the gcc version, limit
the version choice in the custom external toolchain.
The rationale being that there is no point in offering that version to
the user if we know before-hand that the gcc version will not work for
that architecture.
All versions below the minimum we support is just made conditional to
that minimum as well, including the "older" entry.
However, this means that the "older" entry is no longer available when
the architecture requires a minimum gcc version. A user who wants to use
a toolchain with a gcc older than the minimum will have no choice but to
realise the toolchain is not suitable (or lie and we would catch that
when checking the gcc version anyway).

The 'include' directive in GNU make supports wildcards, but their
expansion has no defined sort order (GLOB_NOSORT is passed to glob()).
Usually this doesn't matter. However, there is at least one case where
it does make a difference: toolchain/*/*.mk includes both the
definitions of the external toolchain packages and
pkg-toolchain-external.mk, but pkg-toolchain-external.mk must be
included first.
For predictability, use ordered 'include $(sort $(wildcard ...))'
instead of unordered direct 'include */*.mk' everywhere.

Since 392b0a26f5 (toolchain-external: default BR2_TOOLCHAIN_EXTERNAL_PATH
to empty), calling 'make clean' or similar can yield a spurious stderr
message:
dirname: missing operand
Try 'dirname --help' for more information.
Which is definitely baffling and unsettling...
It turns out that it is pretty trivial to reproduce, and this defconfig
is just enough:
$ cat my-defconfig
BR2_TOOLCHAIN_EXTERNAL=y
$ make BR2_DEFCONFIG=$(pwd)/my-defconfig defconfig
$ make clean
dirname: missing operand
Try 'dirname --help' for more information.
[--snip--]
This is because the cross-compiler is not found in the PATH (and for
good reasons, I don't have it in the PATH, not even at all).
So, when the cross-compiler is not found in the path, we simply
continue as if all was good, and postpone the check to much later,
when we try to copy the toolchain libs...
So, use a make construct rather than calling to the shell: $(dir ...)
does not whine if passed nothing.

The big.LITTLE configurations can be optimised for by gcc, and a few
users wonder what they should choose when they have such CPUs.
Add new entries for those big.LITTLE configurations.
Note: the various combos were added in various gcc versions, but only
really worked in later versions:
Variant | Introduced in | First built in
----------+---------------+----------------
a15-a7 | 4.9 | 4.9
a17-a7 | 5 | 5

-mnan option was added in gcc-4.9.0 so make sure that users cannot
select the NaN mode when using toolchains that have a gcc older
than 4.9.0, and also make sure that the -mnan option is not passed at
all to the toolchain-wrapper and target cflags.

MIPS32 support different FP modes (32,xx,64), so give the user the
opportunity to choose between them. That will cause host-gcc to be built
using the --with-fp-32=[32|xx|64] configure option. Also the
-mfp[32|xx|64] gcc option will be added to TARGET_CFLAGS and to the
toolchain wrapper.
FP mode option shouldn't be used for soft-float, so we add logic in the
toolchain wrapper if -msoft-float is among the arguments in order to not
append the -fp[[32|xx|64] option, otherwise the compilation may fail.

MIPS supports two different NaN encodings, legacy and 2008. Information
about MIPS NaN encodings can be found here:
https://sourceware.org/binutils/docs/as/MIPS-NaN-Encodings.html
NaN legacy is the only option available for R2 cores and older.
NaN 2008 is the only option available for R6 cores.
R5 cores can have either NaN legacy or NaN 2008, depending on the
implementation. So, if the user selects a generic R5 target architecture
variant, we show a choice menu with both options available. For well
known R5 cores we directly select the NaN enconding they use.

It makes no sense to default to an arbitrary path. In addition, it in
fact works correctly when it is empty. In that case, the toolchain will
be searched in PATH.

is supposed to be in the bin subdirectory.

libgcc_s.so is now added to TOOLCHAIN_EXTERNAL_LIBS for glibc/uclibc
in one place, and for musl in another place. Bottom line: it should be
in TOOLCHAIN_EXTERNAL_LIBS unconditionally.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Currently, for the dynamic loader, we're copying ld*.so* for glibc and
uClibc, except for glibc/EABIhf where we are explicitly copying
ld-linux-armhf.so.*. For musl, we're not copying the dynamic linker
because it's simply a symbolic link to libc.so. However, the name of
the musl dynamic linker changes from one architecture to the other,
and we don't handle all cases.
Since handling the musl dynamic linker symlink creation is becoming
more and more annoying to maintain, this commit makes musl use the
same mechanism as glibc/uClibc: put the dynamic linker in
TOOLCHAIN_EXTERNAL_LIBS.
In addition, the special condition on glibc/EABIhf was added in
11ec38b695 ("toolchain-external: fix
Linaro ARM toolchain support") because an old Linaro toolchain had two
dynamic loaders, and we wanted to copy only one. But 1/ this is old
and 2/ having the two dynamic linkers doesn't really matter.
So this commit simply unconditionally adds "ld*.so*" to
TOOLCHAIN_EXTERNAL_LIBS, regardless of the C library being chosen. It
re-uses the musl dynamic linker symlink from the sysroot, which makes
it always correct, and allows us to remove the
TOOLCHAIN_EXTERNAL_MUSL_LD_LINK hook, and all the related logic.
This commit therefore solves two problems with the musl dynamic linker
symbolic link creation logic:
1 We support all architectures, without having to hardcode in
Buildroot the mapping between the CPU architecture and the
corresponding dynamic linker name. For example, our current logic
was not handling the mips64+n32 ABI case, where the dynamic linker
is named ld-musl-mipsn32el.so.1.
2 We support Crosstool-NG musl toolchains, where the dynamic linker
is in /lib, but libc.so is in /usr/lib.

This commit therefore replaces:
- https://patchwork.ozlabs.org/patch/780411/ (was another solution
for solving problem 1 above)
- https://patchwork.ozlabs.org/patch/763977/ and
https://patchwork.ozlabs.org/patch/748974/ (was another solution
for solving problem 2 above)
We currently use $(HOST_DIR)/usr as the prefix for host packages. That
has a few disadvantages:
- There are some things installed in $(HOST_DIR)/etc and
$(HOST_DIR)/sbin, which is inconsistent.
- To pack a buildroot-built toolchain into a tarball for use as an
external toolchain, you have to pack output/host/usr instead of the
more obvious output/host.
- Because of the above, the internal toolchain wrapper breaks which
forces us to work around it (call the actual toolchain executable
directly). This is OK for us, but when used in another build system,
that's a problem.
- Paths are four characters longer.
To allow us to gradually eliminate $(HOST_DIR)/usr while building
packages, replace it with a symlink to .
The symlinks from $(HOST_DIR)/usr/$(GNU_TARGET_NAME) and
$(HOST_DIR)/usr/lib that were added previously are removed again.
Note that the symlink creation will break when $(HOST_DIR)/usr
already exists as a directory, i.e. when rebuilding in an existing
output directory. This is necessary: if we don't break it now, the
following commits (which remove the usr part from various variables)
_will_ break it.
At the same time as creating this symlink, we have to update the
external toolchain wrapper and the external toolchain symlinks to go
one directory less up. Indeed, $(HOST_DIR) is one level less up than
it was before.

Since glibc 2.17, executable link command need not include the -lrt option for
clock_* system calls. As a result, over time less and less software packages
bother to check whether to toolchain needs -lrt. We are now at a point where
maintainers refuse to add this complexity into their build system. This
requires Buildroot to carry patches fixing this issue indefinitely.
glibc 2.17 is now 4.5 years old. There is no reason to use an older version
with current software.
This commit removes the predefined profile for CodeSourcery sh toolchain that
is based on glibc 2.16. One may still use the custom external toolchain
support in Buildroot to get this toolchain back, and deal with any build
issues that this toolchain causes.

The external toolchain code has some logic to calculate the correct name
for the dynamic linker symbolic link that needs to be created when the
musl C library is being used. There was already some handling for the
mipsel+soft-float case, but not for the mips+soft-float case. Due to
this, the symbolic link was incorrectly named, and programs were
referencing an non-existing file.
