c9e5b04230 toolchain/helpers.mk: remove unused argument of check_arm_abi
The check_arm_abi function takes as second argument the path to the
cross-readelf, but does not use it. Therefore, this commit gets rid of
this unnecessary argument.

3b328897f5 toolchain-external: improve musl external check
The current test to verify if the toolchain uses musl or not is based on
checking if /lib/libc.so or /lib/libm.so exist in the sysroot. However,
some toolchains (notably Crosstool-NG ones) put these libraries in
/usr/lib/.

To fix this, build a minimal C program and check if the program
interpreter contains /lib/ld-musl.

9397bd643d toolchain-external: fix definition of TOOLCHAIN_EXTERNAL_READELF
TOOLCHAIN_EXTERNAL_READELF is defined to
$(TOOLCHAIN_EXTERNAL_CROSS)readelf$(TOOLCHAIN_EXTERNAL_SUFFIX), where
TOOLCHAIN_EXTERNAL_SUFFIX is .br_real for Buildroot
toolchains. However, this is bogus, because readelf is not wrapped by
the Buildroot toolchain wrapper, so "<arch>-readelf.br_real" never
exists.

Therefore, it should simply be defined as
$(TOOLCHAIN_EXTERNAL_CROSS)readelf. Currently,
TOOLCHAIN_EXTERNAL_READELF is not used anywhere, so it wasn't visible,
but a follow-up commit will make use of it.

06cd604ec6 toolchain/external: use -dumpversion to check gcc version
Currently, `--version` option is used and later matched with a regex to get
the actual gcc version.  There's a dedicated gcc option to do exactly that:
`-dumpversion`.

Also `--version` may return a string customised by a vendor that provides
the toolchain, which makes the current regex approach error prone.  In
fact, this situation has been seen with a real customised toolchain.

bb924a0489 toolchain-external: fix broken handling of 'usr/lib/locale'
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.

a07e47a47f toolchain-external: reduce nesting in copy_toolchain_sysroot
As discussed with Thomas Petazzoni, we can reduce the nesting level by early
returning on an invalid iteration.

I did not move the 'else' case (the common case) outside the if-else because
it would make the code less symmetrical and IMO makes it _less_ clear.

c69b14fe2f core/pkg-cmake: provide our own platform description
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
pointing to the relevant messages! :-)

To be noted: Thomas suggested we set these directly in the toolchain
file. Unfortunately, wherever we put those settings in the toolchain
file, this does not work.

1c8c0d91a4 Revert "reproducible: fix DATE/TIME macros in toolchain-wrapper"
This reverts commit 76838f6341.

The commit referenced above explicitly states that the function was
copied as-is from the gcc source code at the time. And indeed that is
exactly how the function appeared in gcc in commit
e3e8c48c4a494d9da741c1c8ea6c4c0b7c4ff934.

However, our toolchain wrapper is "GPLv2 only", while the file this function
was copied from is "GPLv3 or later".  As such we can't include that function
and still comply to both licenses.

Furthermore, the code is far from optimum.

Since this feature is not release-critical, revert it until we re-implement
it.

76838f6341 reproducible: fix DATE/TIME macros in toolchain-wrapper
The use of the __DATE__ and __TIME__ macros are one of the most common
sources of non-reproducible binaries. In order to fix that, gcc 7 supports
the SOURCE_DATE_EPOCH variable:

https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=e3e8c48c4a494d9da741c1c8ea6c4c0b7c4ff934

This patch take advantage of toolchain-wrapper to provide support of
SOURCE_DATE_EPOCH to older gcc versions.

Function get_source_date_epoch() come directly from gcc git.

This work was sponsored by `BA Robotic Systems'.

Sync external prebuilt toolchain with the one we now build in Buildroot,

it works pretty fine for building packages in Buildroot.

Still note:
 1) There might be subtle differences between uClibc configuration
    compared to Buildroot's one.
 2) A couple of patches we apply on top of Builroot-built toolchain
    are obviously missing in the prebuilt version - they will be

suppressions to be effective. musl does not define this macros, so add an
unconditional definition of __USE_MISC to libc-compat.h.

In addition, since musl define IFF_LOWER_UP and friends as macros (instead of
enums), define __UAPI_DEF_IF_NET_DEVICE_FLAGS_LOWER_UP_DORMANT_ECHO to
suppress the kernel corresponding definitions to avoid conflict.

in fact also be used to generate 32 bits code for ARMv8 platforms. This
commit therefore adjusts their architecture dependency.

Example, a 32 bits ARM build produces a 32 bits busybox binary:

$ file output/target/bin/busybox
output/target/bin/busybox: setuid ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=16a7a70eb9cac08759e52a260478b9c287f59238, stripped

Which was built for Cortex-A72:

311bc137da toolchain: kill ADI Blackfin toolchain
This toolchain has many problems which are fixed in contemporary gcc
and uClibc-ng. In addition, several hacks are needed to be able to
work with this toolchain. All these hacks are removed as well.  Also
the package exceptions for this toolchain are removed.

The BR2_BFIN_INSTALL_FDPIC_SHARED and BR2_BFIN_INSTALL_FLAT_SHARED
options don't get a legacy entry. For the ADI toolchain, there already
is a legacy entry, so it doesn't make sense to add it twice. For other
external toolchains, these options didn't actually work, because they
rely on the specific layout of the ADI toolchain.

006ba68a30 toolchain-external: support gcc < 4.3
We currently support gcc as old as 4.3. However, Buildroot works
perfectly well with even older gcc versions (tested with 4.1). So we
can add an option BR2_TOOLCHAIN_EXTERNAL_GCC_OLD to support that. The
help text of this option is written with plenty of discouragement.

We use _OLD and not something like _PRE_4_3, because at some point we
will likely remove the 4.3 option and what would then require a name
change.

We don't set any _AT_LEAST option in this case because it's no use -
there is no lower bound on the version in this case. We therefore leave
BR2_TOOLCHAIN_GCC_AT_LEAST empty (the implicit default). When it is
empty, we don't do a version check at all in check_gcc_version
(previously we errored out when it was empty).
