b2ec7830b6 toolchain-external: add support for musl toolchain on ARM EABIhf
Since a few releases, the pre-built musl external toolchain has added
an ARM EABIhf variant, built for ARMv5T. This commit allows this
additional external toolchain to be used.

fa6473729c musl: add a sys/queue.h implementation
Musl does not provide a 'sys/queue.h' implementation, and this has been
a problem for packages that depend on it.

So lets create a package called netbsd-queue that will install a
'sys/queue.h' in the staging directory when enabled, based on the
NetBSD implementation.

Musl toolchain and external toolchain packages will depend on this
package, so that 'sys/queue.h' will be always installed when compiling
with a musl based toolchain.

Tested on ARM and x86 in the following cases:
  - Buildroot musl toolchain.
  - External musl toolchain without 'sys/queue.h'.
  - External musl toolchain with 'sys/queue.h'.

Fixes:

And possibly many others.

b731dc7bfb toolchain-external: make extraction idempotent
Commit 23ffa7ec first extracts to the toolchain-external build
directory and then moves everything to $(HOST_DIR)/opt/ext-toolchain.
However, this is not idempotent, because moving directories over
existing ones doesn't always work, particularly if the target is on
another device.

Simply remove the destination contents before moving.

23ffa7ecf7 toolchain/external: use generic extract commands (!blackfin case)
Now that packages can provide a list of files to be excluded when
extracting their archive, downloaded external toolchains are no longer
special in this respect.

Still, those toolchains are currently extracted directly into their
final location, $(HOST_DIR)/opt/ext-toolchain/ which means we still
need a custom extract command.

Except, we don't really need it: we can just move the toolchain, after
it's been extracted by the generic extract command, with a post-extract
hook.

This means that:

  - we now extract the toolchain with the generic extract command,

  - the toolchain is thus extracted into $(@D) ,

  - fixup commands are run against $(@D), as a post-extract hook,
    instead of against $(HOST_DIR)/opt/ext-toolchain ,

  - once this is done, we move $(@D)/* into the final location with a
    new post-extract hook.

Note: the blackfin case is special, and will be handled in a follow-up
patch.

[Thomas: register the TOOLCHAIN_EXTERNAL_FIXUP_CMDS only for the Arago
case, add some additional comments in the code about why we're moving
the toolchain around.]

32e2636c51 toolchain/wrapper: fix potential bug in foreach loop
In Makefile, the comma ',' is used to separate the arguments passed to
functions, so we should not be allowed to use straight commas in strings
we want to expand.

For the toolchain wrapper, we need to transform a list:
    -mfoo -mbar -mbuz

into something acceptable for a C array assignment:
    "-mfoo", "-mbar", "-mbuz",

So, we use a $(foreach ...) loop for that. However, we do have a
straight comma in there.

It does not cause any issue in practice, since $(foreach) is a make
builtin function that accepts three and only three parameters.

However, this is not sane.

Change the straight comma to the usual $(comma) expansion, like we would
do for a call to any other function.

At the same time, make the code a bit easier to read, by first creating
the transformed list, and then creating the define.

5ce73dca52 toolchain-external: bypass buildroot wrapper
The buildroot internal toolchain now adds a wrapper. When we use a
buildroot toolchain as an external toolchain, we want to bypass this
wrapper and call the compiler directly, for two reasons:

1. The options added by the wrapper are not necessarily appropriate
   when it is reused as an external toolchain. For instance, ccache
   may have been enabled while building the toolchain but not when
   using it as an external toolchain.

2. Currently, the wrapper expects to reside in .../usr/bin, but when
   used as an external toolchain it will be in .../ext-toolchain/bin.
   Therefore, the wrapper can't find the real binary and sysroot
   anymore.

To bypass the wrapper, we check for the existence of *.br_real files in
the external toolchain directory. If any such file exists, the wrapper
will add the .br_real suffix for all the wrapped files. Note that the
wrapper doesn't check if the *.br_real exists for each individual
wrapped file, it just assumes that all wrapped files have a
corresponding .br_real. This is currently true but that may change in
the future of course.

1e97b27873 ccache: support changing the output directory
When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).

Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.

In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

object files than before) and does 'make clean all', ccache may in fact
reuse object files from the previous run. This rarely gives problems,
because
(1) the cache expires quite quickly (it's only 1GB by default),
(2) radically changing compiler options will cause cache misses because
    different header files are used,
(3) many compiler changes (e.g. changing -mtune) have little practical
    effect because the resulting code is usually still compatible,
(4) we currently don't use CCACHE_BASEDIR, and almost all object files
    will contain an absolute path (e.g. in debug info), so when
    building in a different directory, most of it will miss,
(5) we do mostly build test, and many of the potential problems only
    appear at runtime.
Still, when ccache _does_ use the wrong cached object files, the
effects are really weird and hard to debug. Also, we want reproducible
builds and obviously the above makes builds non-reproducible. So we
have a FAQ entry that warns against using ccache and tells the user to
clear the cache in case of problems.

Now that ccache is called from the toolchain wrapper, it is in fact
possible to at least use the 'mtime' compiler hash for the external
toolchain and for the host-gcc. Indeed, in this case, the compiler
executable comes from a tarball so the mtime will be a good reference
for its state. Therefore, the patch (sed script) that changes the
default from 'mtime' to 'none' is removed.

For the internal toolchain, we can do better by providing a hash of
the relevant toolchain options. We are only interested in things that
affect the compiler itself, because ccache also processes the header
files and it doesn't look at libraries because it doesn't cache the
link step, just compilation. Everything that affects the compiler
itself can nicely be summarised in $(HOST_GCC_FINAL_CONF_OPTS). Of
course, also the compiler source itself is relevant, so the source
tarball and all the patches are included in the hash. For this purpose,
a new HOST_GCC_XTENSA_OVERLAY_TAR is introduced.

The following procedure tests the ccache behaviour:

 Use this defconfig:
BR2_arm=y
BR2_CCACHE=y

 make
 readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os
-> Tag_CPU_name: "ARM926EJ-S"

 Now make menuconfig, change variant into BR2_cortex_a9

 make clean; make
 readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os
-> Tag_CPU_name: "ARM926EJ-S"
 should be "Cortex-A9"

After this commit, it is "Cortex-A9".

792f1278e3 toolchain-wrapper: support change of BR2_CCACHE
By moving the ccache call to the toolchain wrapper, the following
scenario no longer works:

make foo-dirclean all BR2_CCACHE=

That's a sometimes useful call to check if some failure is perhaps
caused by ccache.

We can enable this scenario again by exporting BR_NO_CCACHE when
BR2_CCACHE is not set, and by handling this in the toolchain wrapper.

d82f69cf10 infra: move ccache handling to the toolchain wrapper
Since we always have a toolchain wrapper now, we can move the ccache
call to the toolchain wrapper.

The hostcc ccache handling obviously stays.

The global addition of ccache to TARGET_CC/CXX is removed, but many
individual packages and infras still add it. This means we have a
chain like this: ccache -> toolchain-wrapper -> ccache -> gcc
However, this is fairly harmless: for cache misses, the inner ccache
just adds overhead and for cache hits, the inner ccache is never
called. Later patches will remove these redundant ccache calls.

As a side effect, perl now supports ccache as well.

919c06c282 gcc: use toolchain wrapper
We have a toolchain wrapper for external toolchain, but it is also
beneficial for internal toolchains, for the following reasons:

1. It can make sure that BR2_TARGET_OPTIMIZATION is passed to the
   compiler even if a package's build system doesn't honor CFLAGS.
2. It allows us to do the unsafe path check (i.e. -I/usr/include)
   without patching gcc.
3. It makes it simpler to implement building each package with a
   separate staging directory (per-package staging).
4. It makes it simpler to implement a compiler hash check for ccache.

The wrapper is reused from the external toolchain. A third CROSS_PATH_
option is added to the wrapper: in this case, the real executable is in
the same directory, with the extension .real.

The creation of the simple symlinks is merged with the creation of the
wrapper symlinks, otherwise part of the -gcc-ar handling logic would
have to be repeated.

The complex case-condition could be refactored with the one for the
external toolchain, but then it becomes even more complex because
they each have special corner cases. For example, the internal
toolchain has to handle *.real to avoid creating an extra indirection
after host-gcc-{final,initial}-rebuild.

Instead of creating the .real files, it would also have been possible
to install the internal toolchain in $(HOST_DIR)/opt, similar to what
we do for the external toolchain. However, then we would also have to
copy things to the sysroot and do more of the magic that the external
toolchain is doing. So keeping it in $(HOST_DIR)/usr/bin is much
simpler.

Note that gcc-initial has to be wrapped as well, because it is used for
building libc and we want to apply the same magic when building libc.

f6ae24379b toolchain-external: move wrapper to toolchain directory
The toolchain wrapper will be reused for the internal toolchain, so it
belongs in the toolchain directory. Also, the ext- prefix is removed
from it. The build commands are moved to a new toolchain-wrapper.mk.

The wrapper arguments that are also relevant for the internal toolchain
wrapper are moved to toolchain-wrapper.mk, the rest stays in
toolchain-external.mk.

While we're at it, move the building of the toolchain wrapper to the
build step of toolchain-external. There is no specific reason to do
this, other than that it fits better semantically. Also remove the
MESSAGE call, otherwise we'd see:
>>> toolchain-external undefined Building
>>> toolchain-external undefined Building toolchain wrapper
/usr/bin/gcc ...
Having an extra "Building toolchain wrapper' message is pointless.

The useless condition on $(BR2_TARGET_OPTIMIZATION) is removed. It was
always true because it wasn't qstrip'ped first, so clearly it works
without that condition as well.

Also rewrapped some comments and removed the 'external' reference.

e4624fce8a toolchain-external: strip trailing slash from autogenerated FOO_SITE
Trailing slashes are going to be declared illegal from FOO_SITE
variables.

But Buildroot internally generates such a variable when using a custom
external toolchain (i.e. BR2_TOOLCHAIN_EXTERNAL_CUSTOM). This is
because TOOLCHAIN_EXTERNAL_SITE is set to
$(dir $(call qstrip,$(BR2_TOOLCHAIN_EXTERNAL_URL))), and $(dir)
leaves a trailing slash.

Fix it using patsubst, just like linux and the bootloaders do.

looked like this (abbreviated for clarity):

>>> toolchain-external undefined Building
>>> toolchain-external undefined Installing to staging directory
>>> toolchain-external undefined Copying external toolchain sysroot to staging...
>>> toolchain-external undefined Building ext-toolchain wrapper
mkdir -p output/host/usr/bin; cd output/host/usr/bin; for i in ...

if test -e output/target/lib/ld-uClibc.so.1; then ln -sf ld-uClibc.so.1 output/target/lib/ld-uClibc.so.0 ; fi
if test -e output/target/lib/ld64-uClibc.so.1; then ln -sf ld64-uClibc.so.1 output/target/lib/ld64-uClibc.so.0 ; fi

All the long lines with conditions and loops in them are not usefull,
so put $(Q) in front of them. The line with mkdir can better be split
on a separate line so the cd stands out more. There are two redundant
semicolons that can be removed. The installation of gdbinit could
use an extra message so the user can see what is going on.

After this commit, the toolchain-external build steps look like this:
>>> toolchain-external undefined Building
>>> toolchain-external undefined Installing to staging directory
>>> toolchain-external undefined Copying external toolchain sysroot to staging...
>>> toolchain-external undefined Building ext-toolchain wrapper
