As proposed initialy by Matthew Fornero [1], commonize the creation of
symlinks from {/usr}/lib to {/usr}/lib/<tuple> for Linaro toolchains.
This symlinks are only required for old Linaro toolchains.

The Codescape toolchain uses a sysroot layout that places them
side-by-side instead of nested like multilibs. A symlink is needed much
like for the nested sysroots which are handled in copy_toolchain_sysroot
but there is not enough information in there to determine whether the
sysroot layout was nested or side-by-side.
For the above reason plus the fact that this is the only toolchain
needing this, better to handle that symlink creation using a hook which
will be executed only when that toolchain is selected.

This reverts commit 9a1e9efe26.
Currently Codescape toolchains cannot be used to generate a big endian
root file system because the support for side by side sysroots is not
complete.
There is a patch [1] waiting in the queue which fixes the issue for the
current version of Codescape toolchains we have, but it will not work
for the next one that is coming. So, instead of messing more with the
toolchain infra I think it's better to handle these specific Codescape
toolchain's weirdness in hooks which won't affect others.

In 2a87b64 (toolchain-external: align library locations in target and
staging dir), copying the libraries from the sysroot to the target was
changed to a simple find-based solution.
To be sure that the staging directory was entered to find the libraries,
in case the variable was pointing to a symlink, the -L clause to find
was used.
However, that causes extraneous libraries to be copied over.
For example, a ct-ng toolchain would have this sysroot (e.g for an arm
32-bit toolchain):
.../sysroot/lib/
.../sysroot/lib32 -> lib
.../sysroot/lib64 -> lib
.../sysroot/usr/lib/
.../sysroot/usr/lib32 -> lib
.../sysroot/usr/lib64 -> lib
Which we would carry as-is to our own sysroot.
But then, in target, our skeleton creates the /lib/ and /usr/lib
directories, with the necessary lib32 or lib64 symlink pointing to it.
In this case, a lib32->lib symlink is created, but no lib64 symlink
since this is a 32-bit architecture.
To copy the required libraries from staging into target, we scan the
staging directory for all occurences of the required libraries, and copy
them over to target, keeping the same directory layout relative to the
sysroot.
For example:
.../sysroot/usr/lib/libfoo.so --> .../target/usr/lib/libfoo.so
.../sysroot/usr/lib32/libbar.so --> .../target/usr/lib32/libbar.so
.../sysroot/usr/lib64/libbuz.so --> .../target/usr/lib64/libbuz.so
So, when we copy over the libraries from our staging to the target
directory, the "find -L .../sysroot -name libblabla.so.*" would find
multiple instances of libblabla, each in the /usr/lib /usr/lib32 and
/usr/lib64 locations (they are all the exact same file, though).
Since we do have the /usr/lib32->lib symlink, all is OK (but there are
two copies going on, which could be avoided). However, since we do not
have the /usr/lib64->lib symlink, the /usr/lib64/ directory is created.
This was very difficult to observe, as no /lib64/ directory is created,
only the /usr/lib64/ one was. To top it off, this only happens with a
merged /usr, which does not seem like not a common case without systemd.
Since the reason to use -L was to be sure to enter our staging
directory, we just need to ensure that the path ends up with a slash, as
was already talked about in this thread:
http://lists.busybox.net/pipermail/buildroot/2016-April/159737.html
After further discussion, it turns out that the original patch came along
because of the confusion between output/staging (which is a symlink) and
$(STAGING_DIR) which expands to output/host/usr/<tupple>/sysroot (which is
never a symlink), so the symlink handling isn't really needed at all.

The toolchain-external logic is roughly:
- populate the staging dir by rsyncing the entire ${ARCH_LIB_DIR} and
usr/${ARCH_LIB_DIR} from sysroot.
- populate the target dir by explictly copying some libraries from sysroot
into target/lib and some other libraries in target/usr/lib, the split
being hardcoded into buildroot regardless of the location in the sysroot.
This means that a library libfoo could be located in:
staging/lib/libfoo.so
target/usr/lib/libfoo.so
When debugging an application that links against this library, gdb will
fruitlessly search for 'usr/lib/libfoo.so' in staging, and then suggest to
use 'set solib-search-path' which is a hack, really.
To solve the problem, we need to make sure that libraries from the toolchain
are installed in the same relative location in staging and target.
Achieve this by:
- replacing the convoluted search for libraries using for+find in sysroot
with a simple find in staging.
- determining DESTDIR for each library individually based on the location in
staging.
- treating LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS equivalently
These changes also allow for the removal of most arguments to
copy_toolchain_lib_root in the method itself and their callers.
Test procedure:
- set configuration for a given toolchain
- make clean toolchain
- find output/target | sort > /tmp/out-before
- apply patch
- make clean toolchain
- find output/target | sort > /tmp/out-after
- diff -u /tmp/out-before /tmp/out-after
The only changes should be some libraries moving from lib to usr/lib or vice
versa. Notable examples being libstdc++ and libatomic.
