Currently, we repeat all the SSP level selection deep down to the
toolchain wrapper itself, where we eventually translate it to the
actual SSP option to use. This is a bit redundant.
Additionally, we will want to check that the toolchain actually
supports that option (for those toolchain where it was backported).
So, move the translation into kconfig, and add the qstrip'ed value
to the additional flags passed to the wrapper. Add it before
user-supplied opitons, to keep the previous behaviour (and allow
anyone crazy-enough to override it with BR2_TARGET_OPTIMIZATION).

GCC uses thunk functions to adjust the 'this' pointer when calling C++
member functions in classes derived with multiple inheritance.
Generation of thunk functions requires support from the compiler back
end. In the absence of that support target-independent code in the C++
front end is used to generate thunk functions, but it does not support
vararg functions.
Support for this feature is currently missing in or1k and xtensa
toolchains.
Add hidden option BR2_TOOLCHAIN_SUPPORTS_VARIADIC_MI_THUNK that
indicates presence of this feature in the toolchain. Add dependency to
packages that require this feature to be built.

Initially we had a port only for ARCv2 cores but then with a simple
change ARCompact cores got supported as well.
So we generalize from BR2_archs to BR2_arcle as we haven't tried to
get glibc working on big-endian ARCs yet.
Also we never bothered to check avaialbility of atomic instructions in
the core but in case of Glibc for ARC this is really a must, so we add
this check here.
Note in case of uClibc we may have system w/o HW atomics but:
1. Only single-core systems are allowed
2. Atomic instructions are emulated via arc_usr_cmpxchg syscall

nsswitch.conf is processed both by the toolchain, nss-mdns and
nss-myhostname without any guaranteed ordering in between.
The toolchain package ensures that nsswitch.conf is available, and the two
nss-* packages tweaks the content, so the toolchain processing should run
before the nss-* ones. Toolchain is a dependency of all the packages, so
ensure this is done by moving the toolchain handling to a
post-target-install hook.
Also move the variable to toolchain/toolchain/toolchain.mk where the virtual

The RELRO/PIE flags are currently passed via CFLAGS/LDFLAGS and this patch
proposes moving them to the toolchain wrapper.
(1) The flags should _always_ be passed, without leaving the possibility
for any package to ignore them. I.e, when BR2_RELRO_FULL=y is used
in a build, all executables should be built PIE. Passing those
options through the wrapper ensures they are used during the build
of all packages.
(2) Some options are incompatible with -fPIE. For example, when
building object files for a shared libraries, -fPIC is used, and
-fPIE shouldn't be used in combination with -fPIE. Similarly, -r
or -static are directly incompatible as they are different link
time behaviors then the intent of PIE. Passing those options
through the wrapper allows to add some "smart" logic to only pass
-fPIE/-pie when relevant.
(3) Some toolchain, kernel and bootloader packages may want to
explicitly disable PIE in a build where the rest of the userspace
has intentionally enabled it. The wrapper provides an option
to key on the -fno-pie/-no-pie and bypass the appending of RELRO
flags.
The current Kernel and U-boot source trees include this option.
8438ee76b06ace36e19a
If using PIE with a older Kernel and/or U-boot version, a backport of these
changes might be required. However this patchset also uses the
__KERNEL__ and __UBOOT__ defines as a way to disable PIE.
NOTE: The current implementation via CFLAGS/LDFLAGS has caused some
build time failures as the conditional logic doesn't yet exist in
Buildroot:

The check_musl function currently builds a program and verifies if the
program interpreter starts with /lib/ld-musl. While this works fine
for dynamically linked programs, this obviously doesn't work for a
purely static musl toolchain such as [1].
There is no easy way to identify a toolchain as using the musl C
library. For glibc, dynamic linking is always supported, so we look at
the dynamic linker name. For uClibc, there is a distinctive
uClibc_config.h header file. There is no such distinctive feature in
musl.
We end up resorting to looking for the string MUSL_LOCPATH, which is
used by musl locale_map.c source file. This string has been present in
musl since 2014. It certainly isn't a very stable or convincing
solution to identify the C library as being musl, but it's the best we
could find.
Note that we are sure there is a libc.a file, because the
check_unusable_toolchain function checks that there is a such a file.

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.

workaround anymore since kernel commit c0bace798436bc (uapi libc compat:

Updated the comment to accordingly.
Tested with the xl2tp package. This package fails to build with older

Verified experimentally by using exception_ptr with m68k_cf5208 and
looking at the value of ATOMIC_INT_LOCK_FREE. ATOMIC_INT_LOCK_FREE=1,
so the issue is present. Also verified that gcc 7.x fixed it also for
cf5208.

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.

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.

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.

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.

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).

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.

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.

Finally there's working ARC port of glibc thanks to Vineet and Cuper!
This port is based on pretty recent glibc's master branch and ARC
changes are being reviewed now in glibc's mailing list.
Thus we again have to use sources from our GitHub but as soon as there's
a glibc release with our patches applied we'll switch to upstream releases
and will drop our glibc GitHub repo alltogether.
Note now we cut tags in glibc repo simultaneously with tags
in Binutils and GCC repos and so to make sure everything works in the best
way we plan to update glibc tag together with Binutils and GCC.
Also note as of today ARCompact (AKA ARCv1 ISA) is not supported in glibc
but we plan to fix it soonish so for now we make glibc intentionally
dependent on archs38.
Also note we are not creating directory "2.26" because all patches for glibc
ver 2.26 applies to arc glibc port.

Some architectures or specific cores do not have support in upstream
gcc. Currently, they are individually listed as exclusions in the
toolchain choice.
This poses a maintainance burden, as the knowledge about what gcc
version supports what architecture is split across many places: the
toolchain choice, the gcc version choice, the external toolchains.
As a first step, add a blind option that architectures or individual
cores may select to indicate they lack support in our internal backend.
Actual use of the option will come in followup patches.

When using an external toolchain that was built with Buildroot and a
merged /usr, the dynamic linker is actually in /usr/lib.
But the check_glibc macro limits the depth it is looking for the dynamic
linker, and misses it when it is in /usr/lib because it is too deep.
We could fix that in two ways: increase the depth in which we look
for it, or follow symlinks. We choose the second solution.
