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.

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.

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.

The external toolchain logic flattens the directory layout in the staging
directory. Regardless of the number of levels present in the extracted
toolchain, libraries are always copied to lib/ and usr/lib/, and directory
symbolic links are provided to make the original paths available as well.
Due to this, the same library may be reachable through a number of paths:
one path without any symbolic link, and one or more paths using directory
symlinks.
Using a direct path in a symlink destination is generally preferred because
it is clearer, but it is also more robust against accidental removal of an
intermediate directory symlink.
Introduce a helper function to simplify a symlink's destination to such a
direct path. This function will be used in a subsequent patch.

The toolchain from the Cavium Octeon SDK has a sysroot layout as follows:
./lib32
./lib32/octeon2

./lib64
./lib64/octeon2
./lib64-fp
./usr
./usr/lib
./usr/lib32

./usr/lib64
./usr/lib64/octeon2
./usr/lib64-fp
./usr/bin
./usr/bin32
./usr/bin32-fp
./usr/bin64-fp
./usr/libexec
./usr/libexec32
./usr/libexec32-fp
./usr/libexec64-fp
./usr/sbin
./usr/sbin32
./usr/sbin32-fp
./usr/sbin64-fp
./usr/include
./usr/share
./sbin
./sbin32
./sbin32-fp
./sbin64-fp
./etc
./var
with the following selections:
- lib64 : default
- lib64/octeon2 : -march=octeon2
- lib64-fp : -march=octeon3
- lib32 : -mabi=n32
- lib32/octeon2 : -mabi=n32 -march=octeon2
- lib32-fp : -mabi=n32 -march=octeon3
In case of '-mabi=n32 -march=octeon2' (but same is true for n64+octeon2)the
original Buildroot toolchain logic would copy both the libraries in
lib32 as the subdirectory lib32/octeon2, which means that every library is
installed twice (but only one of each is really needed).
While ARCH_LIB_DIR is determined by the location of libc.a, which in this
case is effectively:
<sysroot>/usr/lib32/octeon2/libc.a
the variable only retains 'lib32' and not 'lib32/octeon2' as expected.
To make Buildroot cope with this style of toolchain layout, we need to adapt
the calculation of ARCH_LIB_DIR to also include the second part.
This, in turn, means that ARCH_LIB_DIR is no longer guaranteed to be a
singular path component, resulting in some additional changes.
Certain older Linaro toolchains actually had the same layout. Libraries were
located in lib/<tuple> rather than lib directly. Previously, this was
handled by adding a toolchain-specific fixup that creates a symlink
lib/<tuple> -> lib, but with this patch this would no longer be needed.
Note that one difference with the Octeon case is that these Linaro
toolchains are not actually multilib, i.e. there is just one location with
the libraries and thus there is no problem with duplicated libraries.

Normally, the Buildroot toolchain logic copies all required libraries from
the external toolchain to the staging directory, including the dynamic
loader ld-*.so.
There are cases, however, where the dynamic loader is _not_ automatically
copied to staging. This happens when the dynamic loader is not inside
ARCH_LIB_DIR itself (e.g. lib64), but instead resides in 'lib' (assume, of
course, that ARCH_LIB_DIR != 'lib').
Currently, this is fixed in a toolchain-specific fixup, e.g. by recreating a
missing symlink or copying over a missing file. Such toolchain specific
fixups are not very nice.
Moreover, in a subsequent patch, the value of ARCH_LIB_DIR changes for some
toolchains, causing them to have the same problem of a missing dynamic
loader. This used to be the case for older Linaro toolchains with libraries
in 'lib/<tuple>': Buildroot used to set ARCH_LIB_DIR=lib but the mentioned
patch changes it to 'lib/<tuple>' instead. As a result, the files directly
under 'lib/' will no longer be copied. There should be none, but the dynamic
loader is a notable exception.
[Note: support for these older Linaro toolchain has been removed in 2016.11]
Instead, copy over the ld.so file(s)/link(s) from the extracted toolchain
into staging, in the central copy_toolchain_sysroot function. The existing
toolchain logic will then handle the copy of these files from staging to
target.
This means the toolchain-specific fixups can be removed.

The copy_toolchain_sysroot helper features a complex rsync loop that copies
various directories from the extracted toolchain to the staging directory.
The complexity mainly stems from the fact that we support multilib toolchain
tarballs but only copy one of the multilib variants into staging.
Increase understandability of this logic by explicitly restricting the
rsync excludes to the iteration of the for loop they are relevant for.
Additionally, update the function comment.
Note: all attempts to reduce duplication between both rsync while keeping
things nice and readable failed. One has to be extremely careful regarding
line continuation, indentation, and single vs double quoting. In the end, a

Function copy_toolchain_sysroot, which is in charge of copying the relevant
bits from the external toolchain to the staging directory, performs an rsync
loop of various directories and excludes the pattern 'usr/lib/locale' with
the intention of skipping the directory <toolchain>/usr/lib/locale.
However, while this worked in the original commit, commit
5628776c4a broke it inadvertently. The
relevant part of the diff:
- rsync -au --chmod=Du+w --exclude 'usr/lib/locale' \
- $${ARCH_SYSROOT_DIR}/$$i $(STAGING_DIR)/ ; \
+ rsync -au --chmod=Du+w --exclude 'usr/lib/locale' \
+ --exclude lib --exclude lib32 --exclude lib64 \
+ $${ARCH_SYSROOT_DIR}/$$i/ $(STAGING_DIR)/$$i/ ; \
Notice how the source directory now contains a trailing slash, which impacts
the way the exclude rules are interpreted. Previously, when 'i' was 'usr',
the exclude of 'usr/lib/locale' would find a match. With the trailing slash,
there will never be a match, unless for a directory 'usr/usr/lib/locale'.
The right rule would have been '--exclude lib/locale'.
However, just that fix does not solve the problem in all cases, in
particular in the (common) case where ARCH_LIB_DIR is 'lib'. This is due
another change in that commit, changing the iterated values of the above
rsync:
- for i in etc $${ARCH_LIB_DIR} sbin usr ; do \
+ for i in etc $${ARCH_LIB_DIR} sbin usr usr/$${ARCH_LIB_DIR}; do \
Due to the fact that we rsync both 'usr' as 'usr/lib' (assuming ARCH_LIB_DIR
is 'lib') we need to add the correct exclude in both cases. But the exclude
is different for both. When i == 'usr', the correct exclude rule would be
'--exclude lib/locale' while when i == 'usr/lib' the correct rule would be
'--exclude locale'.
Since we would like to avoid separate cases for this, use the following
exclude: '--exclude locale/'. The trailing slash will make sure only
directories called 'locale' will match. The targeted directories are then
usr/lib/locale and usr/share/locale. The latter directory was not matched
originally, but it should not hurt changing that.

The handling of RPATH in cmake-3.7 has changed drastically, causing a
slew of build failures dues to libraries from the host being pulled in:
- domoticz : http://autobuild.buildroot.org/results/fd0/fd0ba54c7abf973691b39a0ca1bb4e07d749593a/
- freerdp : http://autobuild.buildroot.org/results/5d4/5d429d0e288754a541ee5d8be515454c5fccd28b/
- libcec : http://autobuild.buildroot.org/results/3f3/3f3593bab7734dd274faf5b5690895e9424cbb89/
- and so on...
The bug was reported upstream [0], which dismissed it altogether [1] as
being expected behaviour, quoting:
I don't think there is anything wrong with that change on its own.
It merely exposed some existing behavior in a new case.
Instead, upstream suggested in that same message that a platform
definition be used instead, quoting:
If a toolchain file specifies CMAKE_SYSTEM_NAME such that a custom
`Platform/MySystem.cmake` file is loaded then the latter can set
them as needed for the target platform.
So here we are doing so:
- we add a new platfom definitions that inherits from the Linux one,
then overrides the problematic settings;
- we change our toolchain file to use that platform instead;
- we tell cmake where to find additional modules, so that it can find
our custom platform file.
This has been tested to work in the following conditions:
- pre-installed host cmake, versions 3.5.1 (Ubuntu 16.04) and 3.7.2
(manually built)
- internal cmake, versions 3.6.3 (the current version as of this
patch) and 3.7.2 (with the followup patches).
Thanks to Jörg, Ben and Baruch for the help investigating the issue.
Special thanks to Jörg for handling the discussion with upstream and

However, our toolchain wrapper is "GPLv2 only", while the file this function

The rework done on commit
accba02a47 ("toolchain: add option for
toolchains affected by GCC PR libstdc++/64735") by me was wrong. The
BR2_TOOLCHAIN_HAS_GCC_BUG_64735 option should be enabled when the bug is
present in the toolchain, not the opposite.

[Thomas:
- directly define the value where BR2_TOOLCHAIN_HAS_GCC_BUG_64735
rather than having additional patches touching affected architectures
Config.in files
- add a better comment above the Config.in option.]
