toolchain: gcc: update 7.x to 7.2.0
Bump gcc from 7.1 to 7.2 Compile & run tested: ar71xx Trace history of current patches and update with commit ref & comment to give more clue as to why they're still around/needed. Some have changed form since the original commit but some clue is better than no clue at all.

gcc/musl: rework SSP-support
|

|

Make musl provide libssp_nonshared.a and make GCC link it unconditionally
|

if musl is used. This should be a no-op if SSP is disabled and seems to be
|
||||
the only reliable way of dealing with SSP over all packages due to the mess
|

that is linkerflags handling in packages.

gcc: prevent the use of LDRD/STRD on ARMv5TE
|
||||
|
||||
These instructions are for 64-bit load/store. On ARMv5TE, the CPU
|
||||
requires addresses to be aligned to 64-bit. When misaligned, behavior is
|
||||
undefined (effectively either loads the same word twice on LDRD, or
|
||||
corrupts surrounding memory on STRD).
|
||||
|
||||
On ARMv6 and newer, unaligned access is safe.
|
||||
|
||||
Removing these instructions for ARMv5TE is necessary, because GCC
|
||||
ignores alignment information in pointers and does unsafe optimizations
|
||||
that have shown up as bugs in various places.

toolchain/gcc: .init and .fini need to pick one ISA
|
||||
|
||||
The .init and .fini sections are built by concatenating code
|
||||
fragments. Putting mips16 code in the middle of a mips32 code block
|
||||
doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
|
||||
|
||||
This is specific to 4.6-linaro but is probably portable to other gcc
|
||||
flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
|
||||
hack not suitable for pushing upstream, but there is no mips/t-linux
|
||||
or mips/t-uclibc and I am not going to touch gcc/configure for two
|
||||
lines.

gcc: don't clobber stamp-bits with a symlink to itself
|
||||
|
||||
Several versions of gcc have an issue in libstdc++v3 where the build may
|
||||
clobber stamp-bits with a link to itself. This doesn't manifest itself
|
||||
on all systems. On several Ubuntu systems, this doesn't appear to be a
|
||||
problem, but it is an issue on Fedora 16 systems.
|
||||
|
||||
To fix the issue, we'll simply filter out stamp-bits from the symlinks
|
||||
to be generated.
|
||||
|
||||
Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
|
||||
there.
