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'.

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.

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.

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.

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.

Our current ccache disables hashing of the compiler executable itself,
because using the default 'mtime' doesn't work in buildroot: we always
rebuild the compiler, so the mtime is always different, so the cache
always misses.
However, in the current situation, if a user changes the compiler
configuration (which would result in the compiler generating different
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".

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.

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.

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

While we're at it, move the building of the toolchain wrapper to the

this, other than that it fits better semantically. Also remove the

Introduced by previous patch 0f75b2635e,
this printf would break the build of glibc, because there is no format
to printf:
printf: usage: printf [-v var] format [arguments]

'echo -n' is not a POSIX construct (no flag support), we shoud use
'printf', especially in init script.
This patch was generated by the following command line:
git grep -l 'echo -n' -- `git ls-files | grep -v 'patch'` | xargs sed -i 's/echo -n/printf/'

When ARCH is arm and the hard-floating-point option is on executables
expect to find the dynamic linker at /lib/ld-musl-armhf.so.1 and not
/lib/ld-musl-arm.so.1.
This patch adjusts the logic that creates the symbolic link from the
dynamic linker path to the musl C library (since musl has everything
built into a single file).
[Thomas: tweak the commit log.]
