b55ff5a7cd toolchain: detect external glibc in merged /usr
When using an external toolchain that was built with Buildroot and a
merged /usr, the dynamic linker is actually in /usr/lib.

But the check_glibc macro limits the depth it is looking for the dynamic
linker, and misses it when it is in /usr/lib because it is too deep.

We could fix that in two ways: increase the depth in which we look
for it, or follow symlinks. We choose the second solution.

6eaa6460ba toolchain/buildroot: not available for a few mips cores
Commit 1b974425 (MIPS: add support for M6201 cores) explained that the
new core was not supported by upstream gcc, and as of gcc-8-trunk
that's still the case.

Ditto for 3cfbeb83 (MIPS: add support for P6600 cores).

This means that we currently allow to build an internal tolchain for
those cores, yet we have no suitable gcc version.

Disable the internal backend in this case.

e4ebf9b0be core/pkg-toolchain-external: quiesce spurious stderr
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.

9a0a0a976b arch/mips: add support for MIPS32 FP mode
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.

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.

015d68c84c toolchain-wrapper: fix breakage after host/usr removal
The toolchain wrapper, when called through PATH, strips the last three
levels of /proc/self/exe to find HOST_DIR. However, after the host/usr
removal, this should be just two levels.

The toolchain wrapper has different logic for when it is called with a
full path (i.e. $HOST_DIR/usr/bin/arm-linux-gcc) then when it is called
through the PATH (i.e. just arm-linux-gcc). The latter is never used
internally in Buildroot, that's why this wasn't discovered through
testing.

b291525ac7 toolchain: replace absolute symlinks by relative symlinks during sysroot copy
In commit 32bec8ee2f
("toolchain-external: copy ld*.so* for all C libraries") we changed
how the musl dynamic linker symbolic link was being created. Instead
of having specific logic in Buildroot, we switched to simply copying
the ld*.so.* symbolic link from staging to target, as well as the
target of this symbolic link.

However, it turns out that by default, musl creates its dynamic linker
symbolic link with an absolute path as the target of the link:
/lib/libc.so.

Therefore, external Musl toolchains built with Buildroot look like
this:

  lrwxrwxrwx 1 thomas thomas      12 Jul  4 19:46 ld-musl-armhf.so.1 -> /lib/libc.so

The principle of the copy_toolchain_lib_root function, which is used
to copy libraries from staging to target, is to copy symbolic links
and follow their targets. In this case, it means we end up copying
/lib/libc.so (from the host machine) into the target folder. From
there on, there are two cases:

 1. /lib/libc.so exists in your host system. It gets copied to the
    target. But later on, Buildroot also copies /lib/libc.so from
    staging to target, overwriting the bogus libc.so. So everything
    works fine, even though it's admittedly ugly.

 2. /lib/libc.so doesn't exist in your host system. In this case, the
    build fails with no clear error message.

This problem does not happen with Musl toolchains built by
Crosstool-NG, because Crosstool-NG replaces the absolute target of the
dynamic linker symbolic link by a relative path.

However, since we want to support existing Buildroot Musl toolchains
and generally work with the fact that Musl by default installs an
absolute symlink, the following commit improves the
copy_toolchain_sysroot function to replace symbolic links with an
absolute destination to use a relative destination. I.e, in staging,
the ld-musl-armhf.so.1 symbolic link looks like this:

lrwxrwxrwx 1 thomas thomas 14 Jul  5 22:59 output/staging/lib/ld-musl-armhf.so.1 -> ../lib/libc.so

9971e936be toolchain/helpers.mk: fix creation of DESTDIR in copy_toolchain_lib_root
In commit b3cc7e65ee, the definition of the DESTDIR variable was moved
down into the loop that follows symlinks in the libraries that are
copied to target. However, the corresponding mkdir was not moved down,
so that no directories are ever created.

In practice, this mkdir is normally redundant since the directories
should already have been created as part of creating STAGING_DIR.
Still, the current situation is clearly wrong, so fix it by moving the
mkdir down to after the assignment to DESTDIR.

While we're at it, also remove a redundant empty line. It's a leftover
from when a lot of variables were declared above.

eb22fe8231 toolchain/helpers.mk: simplify ld.so fixup in copy_toolchain_sysroot
In copy_toolchain_sysroot, if no ld.so has been found in the
STAGING_DIR after the sysroot copy, we look at ARCH_SYSROOT_DIR if a
ld.so is available there. We do this for both ld*.so and ld*.so.*.

However, when copying thing from staging to target (as listed in
TOOLCHAIN_EXTERNAL_LIBS), we only match on ld*.so.*. This would mean
that even if a dynamic linker matching ld*.so but not ld*.so.* was
copied into staging by copy_toolchain_sysroot, it would anyway not be
copied to the target filesystem, making the system unusable.

Therefore, we can remove the special case on ld*.so, and keep only
ld*.so.*.

32bec8ee2f toolchain-external: copy ld*.so* for all C libraries
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.

b3cc7e65ee toolchain/helpers.mk: re-evaluate DESTDIR in copy_toolchain_lib_root
copy_toolchain_lib_root copies libraries from staging to target,
resolving and copying symbolic links along the way.

The most inner loop, a "while" loop, starts from an initial name, and
if it's a symbolic link, gets resolved to the target, and the loop
iterates until we reach a real file. However, the destination folder
where the symbolic link or real file is created is computed in DESTDIR
only once, before this loop starts. Therefore, this loop works fine
when all symbolic links in the chain, and the real file all belong to
the same directory. But it doesn't do the correct thing when the
symbolic link and/or real file are in different folder.

An example is Crosstool-NG musl toolchains, where the dynamic loader
is in /lib/ld-musl*.so but points to ../usr/lib/libc.so. With the
current logic, we copy /lib/ld-musl*.so to /lib, but we also copy
libc.so to /lib instead of the expected /usr/lib.

This currently doesn't cause any problem because the musl dynamic
linker is manually created by the TOOLCHAIN_EXTERNAL_MUSL_LD_LINK
hook. However, this logic has a number of problems, so in a followup
commit, we are going to put the musl dynamic linker in
TOOLCHAIN_EXTERNAL_LIBS, which will cause it to be copied by
copy_toolchain_lib_root. But we obviously want the link and its target
to be copied to the right place, hence this fix.

14151d77af Eliminate $(HOST_DIR)/usr
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.

6510a826e1 toolchain: remove CodeSourcery sh toolchain
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

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.

06cac6460f toolchain: remove CodeSourcery x86 toolchain
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.

is based on glibc 2.16. One may still use the custom external toolchain

a6a4a8b2ef toolchain-external: adjust musl dynamic linker symlink for mips-sf
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.

Add a new patch to allow to build gcc 7.1 without extracting gcc/testsuite
directory.

This new gcc version require a kernel patch [1] to avoid a build issue with
____ilog2_NaN symbol. The following kernel version contain contain already
this patch :
4.11, 4.10.6, 4.9.18, 4.4.57, 3.18.50 and 3.12.73.

To build a toolchain based on gcc 7 and uClibc-ng 1.0.24, the patch [2] is
required to avoid a build issue due to missing aligned_alloc() definition.

a7fda62eec toolchain-external: fix handling of ld.so
Commit ba6bac1383 made a change in copying of
the dynamic loader, with the goal of reducing toolchain-specific fixups.
Any ld*.so file found in the toolchain's lib directory would be copied to
the staging/lib directory.

For the toolchains that previously needed fixup, this new behavior is fine.
The reason they needed fixup was that the normal copy action did not include
any dynamic loader.

However, for certain other toolchains this new behavior actually breaks
things: regardless of ARCH_LIB_DIR, which may be lib64 instead of lib, the
dynamic loader from lib is copied _over_ any previously correct dynamic
loader.

This has been witnessed with the CodeSourcery x86_64 and
CodeSourcery MIPS64 toolchains. In both cases, a 32-bit dynamic loader was
copied to staging/lib, while a 64-bit version was expected.

Fix the problem by only performing this explicit dynamic loader copy if no
dynamic loader is found in staging/lib.

38b51739da toolchain: copy_toolchain_lib_root: copy symlinks instead of recreating them
copy_toolchain_lib_root handles symlinks by recreating them, disregarding
the original destination and assuming the destination is in the same
directory as the link itself.
When a library link points to the real library file in another directory,
for example:
    usr/lib/octeon2/libcrypt.so -> ../../../lib32/octeon2/libcrypt.so.1
then the link created by copy_toolchain_lib_root is broken.

It is more robust to copy the symlink to keep the destination intact. The
destination path should be present, possibly through other symbolic links.

9e4fb2019b toolchain: copy_toolchain_lib_root: clarify input parameter
The input to copy_toolchain_lib_root is not one library, not a list of
libraries, but a library name pattern with glob wildcards.
This pattern is then passed to 'find' to get the actual list of libraries
matching the pattern. Reflect this using an appropriate variable name.

Note: if the root of the buildroot tree contains a file matching one of
these library patterns, the copying of libraries from staging to target will
not be correct. It is not impossible to fix that, e.g. using 'set -f', but
maybe it's not worth it.
