928c9289d2 toolchain-external-custom: allow specifying relative path to binaries
There are cases where a downloaded toolchain doesn't have its binaries
placed directly in a "bin" subfolder (where BuildRoot currently looks
for them).

A common example is the official Raspberry Pi Toolchain
(https://github.com/raspberrypi/tools), which has its binaries in
"arm-bcm2708/arm-linux-gnueabihf/bin".

This commit introduces BR2_TOOLCHAIN_EXTERNAL_REL_BIN_PATH that defaults
to "bin" and can be changed as needed.

5e58509bfe toolchain-wrapper: use -ffp-contract=off on MIPS Xburst for gcc >= 4.6
Since gcc 4.6, GCC deprecated -mfused-madd, -ffp-contract=off should
be used for the Xburst workaround.

Tested with the MIPS Sourcery 2011.03 toolchain (based on gcc 4.5),
the toolchain wrapper uses -mno-fused-madd, as expected:

$ BR2_DEBUG_WRAPPER=2 ./output/host/bin/mips-linux-gnu-gcc -o toto toto.c
Toolchain wrapper executing:
    '/home/thomas/toolchains/mips-2011.03/bin/mips-linux-gnu-gcc'
    '--sysroot'
    '/home/thomas/projets/buildroot/output/host/mipsel-buildroot-linux-gnu/sysroot'
    '-mabi=32'
    '-msoft-float'
    '-mno-fused-madd'
    '-EL'
    '-march=mips32r2'
    '-o'
    'toto'
    'toto.c'

And with the MIPS Sourcery 2012.09 toolchain (based on gcc 4.7), the
toolchain wrapper uses -ffp-contract=off, as expected:

$ BR2_DEBUG_WRAPPER=2 ./output/host/bin/mips-linux-gnu-gcc -o toto toto.c
Toolchain wrapper executing:
    '/home/thomas/toolchains/mips-2012.09/bin/mips-linux-gnu-gcc'
    '--sysroot'
    '/home/thomas/projets/buildroot/output/host/mipsel-buildroot-linux-gnu/sysroot'
    '-mabi=32'
    '-msoft-float'
    '-ffp-contract=off'
    '-EL'
    '-march=mips32r2'
    '-o'
    'toto'
    'toto.c'

Rearrange the header of the .mk file so it becomes similar to a header
from a package. It doesn't fit in one line, so split the details to a
comment below the header.

GCONV_LIBS is only used inside this file, so rename it to start with
TOOLCHAIN_, following the namespace convention already used by packages.

following the convention used for hooks in packages.

Move the raw contents from the file to the exact location it is

6729050f3a pkg-cmake: install CMake files as part of a package
Currently, the toolchainfile.cmake and Buildroot.cmake files are
installed outside of any package, just triggered by the toolchain
target.

As part of the per-package SDK effort, we are trying to avoid anything
that installs to the global $(HOST_DIR), and this is one of the
remaining files installed in $(HOST_DIR) outside of any package. We
fix this by installing such files as part of the toolchain package
post-install staging hooks.

Yes, a post-install staging hook to install things to $(HOST_DIR) is a
bit weird, but the toolchain infrastructure is made of target packages
only, and they all install a lot of stuff to $(HOST_DIR) already.

6afee03e3c toolchain: limit musl/kernel headers conflict workaround
The musl/kernel headers workaround was added in commit 196932cd91
(toolchain: workaround musl/kernel headers conflict) to fix definition
collisions in networking related headers between musl headers and kernel
headers. Kernel headers from version 4.15 and newer do not need this
workaround anymore since kernel commit c0bace798436bc (uapi libc compat:
add fallback for unsupported libcs). The C library does not have to
define the __GLIBC__ macro to make the __UAPI_DEF_* macros effective.

Updated the comment to accordingly.

Tested with the xl2tp package. This package fails to build with older
kernel headers without the workaround (struct in_pktinfo redefinition,
among others). With 4.15 headers, xl2tp builds fine with this patch
applied. That is, no workaround needed.

1a69e33d57 toolchain: post-pone evaluation of TOOLCHAIN_EXTERNAL_BIN
The upcoming per-package SDK functionality is heavily based on the
fact that HOST_DIR, STAGING_DIR and TARGET_DIR are evaluated during
the configure/build/install steps of the packages. Therefore, any
evaluation-during-assignment using := is going to cause problems, and
need to be turned into evaluation-during-use using =.

This patch fix up one such instance in the external toolchain code.

This change is independent from the per-package SDK functionality, and
could be applied separately.

This merges the next branch accumulated during the 2017.11 release
cycle back into the master branch.

A few conflicts had to be resolved:

 - In the DEVELOPERS file, because Fabrice Fontaine was added as a
   developer for libupnp in master, and for libupnp18 in
   next. Resolution is simple: add him for both.

 - linux/Config.in, because we updated the 4.13.x release used by
   default in master, while we moved to 4.14 in next. Resolution: use
   4.14.

 - package/libupnp/libupnp.hash: a hash for the license file was added
   in master, while the package was bumped into next. Resolution: keep
   the hash for the license file, and keep the hash for the newest
   version of libupnp.

 - package/linux-headers/Config.in.host: default version of the kernel
   headers for 4.13 was bumped to the latest 4.13.x in master, but was
   changed to 4.14 in next. Resolution: use 4.14.

 - package/samba4/: samba was bumped to 4.6.11 in master for security
   reasons, but was bumped to 4.7.3 in next. Resolution: keep 4.7.3.

9ab3058e09 toolchain/buildroot: add comment for glibc NaN-2008 headers requirement
Commit 4a5140ecf (toolchain/buildroot: glibc requires kernel headers >=
4.5 with NaN-2008) added a restriction on kernel headers for glibc when
the architecture is using naN-2008.

However, such a restriction is usually associated to a comment explaining
the restriction, so the user knows what is happening.

That comment was forgotten in 4a5140ecf. Add it now.

For armv8, there are different profiles: A, M and R, like there is for
armv7.

So, rename our internal symbol to mirror what we do for armv7.

e25d704e10 arch/mips: inverse the mfpxx logic
Currently, the possibility to choose the floating point mode (32, xx or
64) is conditional on having a sufficiently recent gcc version.

Which means that the architecture selection depends on the gcc version.

But that's opposite to what we've always done in Buildroot: the software
versions are conditional to the architecture options. There is nothing
we can do about the hardware: it is there, we can't change it, while we
can restrict ourselves to using software that is working on said
hardware.

Thus, we inverse the logic, to move the condition onto the software
side: whenever mfpxx is selected, we restrict the toolchain selection to
at least a gcc-5.

And now, the blind BR2_TOOLCHAIN_HAS_MFPXX_OPTION symbol is no longer
needed, so we get rid of it.

d08ccb40f5 arch/arm: some variants need different gcc versions
Take the conditions currently specified in the gcc version choice.

Also, the conditions explained in the commit log for 78c2a9f7 were not
all properly applied, especially the a57-a53 combo needs gcc-6, but
78c2a9f7 forgot to add the condition to gcc-4.9.

gcc-4.9 was excluded for cortex-a17 and a72, but the CodeSourcery
external toolchain, which uses 4.8, was not excluded for those two
cores. Now it is.

Remove the arch condition from gcc and the external toolchains.

3ae7f68b59 toolchain/external-custom: hide versions too old for the current arch
When an architecture expresses a requirement on the gcc version, limit
the version choice in the custom external toolchain.

The rationale being that there is no point in offering that version to
the user if we know before-hand that the gcc version will not work for
that architecture.

All versions below the minimum we support is just made conditional to
that minimum as well, including the "older" entry.

However, this means that the "older" entry is no longer available when
the architecture requires a minimum gcc version. A user who wants to use
a toolchain with a gcc older than the minimum will have no choice but to
realise the toolchain is not suitable (or lie and we would catch that
when checking the gcc version anyway).

b9d2d4cb4e Fix makefile include order by using sort/wildcard.
The 'include' directive in GNU make supports wildcards, but their
expansion has no defined sort order (GLOB_NOSORT is passed to glob()).
Usually this doesn't matter. However, there is at least one case where
it does make a difference: toolchain/*/*.mk includes both the
definitions of the external toolchain packages and
pkg-toolchain-external.mk, but pkg-toolchain-external.mk must be
included first.

For predictability, use ordered 'include $(sort $(wildcard ...))'
instead of unordered direct 'include */*.mk' everywhere.

Fixes [1] reported by Petr Vorel:

  make: *** No rule to make target 'toolchain-external-custom', needed by '.../build/toolchain-external/.stamp_configured'.  Stop.

6393b6904b toolchain/wrapper: fake __DATE_ and __TIME__ for older gcc
Starting with version 7, gcc automatically recognises and enforces the
environment variable SOURCE_DATE_EPOCH, and fakes __DATE__ and __TIME__
accordingly, to produce reproducible builds (at least in regards to date
and time).

However, older gcc versions do not offer this feature.

So, we use our toolchain wrapper to force-feed __DATE__ and __TIME__ as
macros, which will take precedence over those that gcc may compute
itself. We compute them according to the specs:
    https://reproducible-builds.org/specs/source-date-epoch/
    https://gcc.gnu.org/onlinedocs/cpp/Standard-Predefined-Macros.html

Since we define macros otherwise internal to gcc, we have to tell it not
to warn about that. The -Wno-builtin-macro-redefined flag was introduced
in gcc-4.4.0. Therefore, we make BR2_REPRODUCIBLE depend on GCC >= 4.4.

gcc-7 will ignore SOURCE_DATE_EPOCH when __DATE__ and __TIME__ are
user-defined. Anyway, this is of no consequence: whether __DATE__ and
__TIME__ or SOURCE_DATE_EPOCH takes precedence, it would yield the
exact same end result since we use the same logic to compute it. Note
that we didn't copy the code for it from gcc so using the same logic
doesn't imply that we're inheriting GPL-3.0.
