Subject: [PATCH] libgcc: use -mno-gnu-attribute for 128-bit IBM ldouble
 support code

Doing this will allow libgcc to emit the appropriate symbols without actually
emitting the FP ABI tag for them, which allows 64-bit long double environments
to function and even link statically while still allowing usage of
explicit __ibm128.
