The gcc.mk file is passing --enable-target-optspace to gcc configure
script, to ask for space-optimized (-Os) target libraries. However,
passing this option has the effect of overriding any custom
CFLAGS_FOR_TARGET or CXXFLAGS_FOR_TARGET values that may be passed.
These are some situations when it is required to pass custom flags on
buildong
of libgcc:
* Default flags "-g -Os" lead to build isses as with PowerPC on gcc 4.5
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810)
* Particular CPU requires specific instructions for HW support
* Deep optimizations

* GCC: C ABI compatibility between MetaWare and GNU toolchains
* uClibc: support for thread local storage and Native Pthread Library (NPTL)
* GDB: updated to version 7.9.1

This combination causes a compilation failure of the host-gcc-final
recipe like this one:
/br/output/host/usr/mips-buildroot-linux-gnu/bin/ld:
.libs/gload.o: relocation R_MIPS_HI16 against `__gnu_local_gp' can not
be used when making a shared object; recompile with -fPIC
The problem is the file 'libatomic/gload.c' is compiled without -fPIC
when using binutils-2.25. All gcc (with libatomic) versions below 4.9.3
are affected by this issue.
Here is a summary of affected/unaffected versions in Buildroot:
4.7.x: unaffected (doesn't have libatomic)
4.8.x: affected
4.9.x: unaffected (we have 4.9.3 which is fixed)
5.1.x: unaffected
The fix can be found here:
57f5c0954f
However, given the following reasons...
- Upstream gcc 4.8 branch is closed.
- The fix is very hard to backport from 4.9 to 4.8.
- This stuff is insanely sensitive and not working at all could be
better than looking like it works but not quite.
...I think the best choice is to disable that combination in Buildroot.

In buildroot we maintain a couple off-the-tree patches.
In particular for binutils and gcc packages.
Because we have many versions of mentioned packages patches for each
particular version reside in a folder which name matches full version
name of the package.
For example we used to have patches for binutils distributed as part of
arc-2014.12 tools in folder ""package/binutils/arc-2014.12". Now with
bump of ARC tools version we need to rename folder with patches to
"arc-2015.06-rc1".
The same applies to gcc.
Should fix http://autobuild.buildroot.net/results/2b2/2b27a4a64c0b225ae479ecfccf7a97f5ea95598c/
As discussed before it's not possible to reproduce reported problem on recent
Fedora 21/22 distros (at least we know about them) but I may confirm that
patches were applied fine and everything was built well. Hopefully reported
build failure goes away now.

Even though this is only RC1 it's been heavily used internally so it should
not be any worse than existing arc-2014.12.
Moreover this relase (and so its RC1) finally delivers support of NPTL
for ARC in uClibc.
That's why it would be good to allow interested users to start trying it
(for example WebKit and apps that use WebKit could be successfully built
and run) also it will be helpful to run that new toolchain through
autobuilder in attempt to find any hidden regressions so we have a solid
toolchain for release.
If there's an interest in that patch more patches will follow with
subsequent RCs and essentially on appearence or relese Buildroot will be
updated with it.

This commit adds support for gcc 5.1 in Buildroot. In terms of gcc
patches, compared to gcc 4.9.x:
* Kept as is, sometimes after minor adjusments:
100-uclibc-conf.patch
301-missing-execinfo_h.patch
810-arm-softfloat-libgcc.patch
830-arm_unbreak_armv4t.patch
840-microblaze-enable-dwarf-eh-support.patch
850-libstdcxx-uclibc-c99.patch
860-cilk-wchar.patch
* Dropped:
110-pr64896.patch
111-pr65730.patch
* Split in multiple parts:
900-musl-support.patch
The patches from Crosstool-NG for muls support are used instead of
one single patch.
* Renamed:
910-gcc-poison-system-directories.patch to
200-gcc-poison-system-directories.patch
920-libgcc-remove-unistd-header.patch to
201-libgcc-remove-unistd-header.patch
Since the 9xx part of the series is now used by the various musl
related patches.
We have tested the following configurations, with a minimal Busybox
system:
* ARM, uClibc-ng
* ARM, glibc
* ARM, musl
* x86, uClibc-ng and uClibc 0.9.33.2
* x86, glibc
* x86, musl
All of the configurations built fine. All the configurations boot fine
in Qemu, except x86/uClibc (either ng or 0.9.33.2), it segfaults when
running init:
devtmpfs: mounted
Freeing unused kernel memory: 300K (c1389000 - c13d4000)
init[1]: segfault at 0 ip b77708c1 sp bfa9bb0c error 4 in ld-uClibc-0.9.33.2.so[b776c000+6000]
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
We'll give some time for the uClibc developers to fix the problem
before taking other measures in Buildroot to exclude gcc 5.1 from a
x86/uClibc configuration.

The Linux kernel does force compile with -m4-nofpu, which is only
available when building a multilib toolchain.
The interesting part here is, that buildroot use --disable-multilib for
gcc configure, but enables --with-multilib-list=m4,m4-nofpu in
the default configuration for Qemu targeting r2d emulation.
This results in a toolchain, which can be used for the kernel and
for userland without creating a multilib toolchain with different
kinds of libgcc version. In the multilib case there would be
subdirectories created (!m4 and m4-nofpu). As buildroot uses a
short version of toolchain creation, a multilib enabled gcc build
fails when creating libgcc.
So the best solution is to just keep multilib disabled, but always
add --with-multilib-list when sh4/sh4eb/sh4a/sh4aeb is choosen.
Tested with sh4/sh4a toolchain build and qemu defconfig with
gcc 4.8.x/4.9.x (with and without C++ enabled), uClibc and glibc.
Disable sh4a/sh4aeb for uClibc, as it does not implemented, yet.

Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with
LTO support.
Individual packages still have to enable LTO explicitly by passing '-flto' to
GCC, which passes it on to the linker. This option does not add that flag
globally. Some packages detect if the compiler supports LTO and enable the flag
if it does.
To support LTO, ar and ranlib must be called with an argument which triggers the
usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead
provides wrappers for ar and ranlib that pass the LTO arguments. This way
existing Makefiles don't need to be changed for LTO support. However, these
wrappers are called <tuple>-gcc-ar which matches the pattern to link to the
buildroot wrapper in the external toolchain logic. So the external toolchain
logic is updated to provide the correct symlink.
[Thomas:
- Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO
support in binutils. This is a blind option, selected by
BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke
directly into gcc Config.in options.
- Remove the check on the AVR32 special gcc version, which we don't
support anymore.
- Adapt the help text of the LTO Config.in option to no longer
mention "Since version 4.5", since we only support gcc >= 4.5 in
Buildroot anyway.
- Fix typo in toolchain-external.mk comment.]

More details about arc-2014.12 release are available here:

* 402-fix-length-of-instructions-that-are-in-delay-slot-and-needs-to-be-predicated.patch
* 403-update-casesi_compact_jump-instruction-length.patch
But since arc-2014.12 tools are still based on GCC 4.8 following patches
ar still relevant so moving to the new folder to match ARC gcc bump.
* 100-libstdcxx-uclibc-c99.patch
* 910-gcc-poison-system-directories.patch

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

/usr/local/include, etc.). The patch was adapted to gcc 4.7.4, and
modified to support the BR_COMPILER_PARANOID_UNSAFE_PATH environment
variable to error out instead of just warn when unsafe paths are
used. Even though erroring out can be chosen by passing
-Werror=poison-system-directories, we are not sure this option in

guarantees it will always be passed, and also allows to have an
identical behavior to the external toolchain wrapper.
