Felix Fietkau 548d9a008f 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.

Felix Fietkau b050f87d13 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.

Jonas Gorski 73b7c776e9 toolchain: gcc: backport fixes for gcc bug 54295
Fix "Widening multiply-accumulate operation uses wrong value extension"
for 4.7, 4.7-linaro and 4.6-linaro, which backported the broken code to 4.6.
Vanilla 4.6 is unaffected.

Fixes #13420.

Florian Fainelli 9dc38e48f7 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.
