[PowerPC]: Don't allow r0 as a target for LD_GOT_TPREL_L/32
Summary:
The linker is free to relax this (relocation R_PPC_GOT_TPREL16) against
R_PPC_TLS, if it sees fit (initial exec to local exec). If r0 is used,
this can generate execution-invalid code (converts to 'addi %rX, %r0,
FOO, which translates in PPC-lingo to li %rX, FOO). Forbid this
instead.
This fixes static binaries using locales on FreeBSD/powerpc
(tested on FreeBSD/powerpcspe).
