PR66870 PowerPC64 Enable gold linker with split stack
A powerpc-linux/powerpc64-linux biarch compiler can default to either
-m32 or -m64, and we need to notice both -m32 and -m64 on the gccgo
command line. It's also possible to build a -m64 only compiler, so in
that case we can define TARGET_CAN_SPLIT_STACK.
