Subject: [PATCH 055/160] Re: PowerPC64 pcrel got relocs against local symbols
The last patch wasn't all that shiny. There are rather a lot more
relocations that can hit the assertion in md_apply_fix if the symbol
is local or absolute. Fix them all.
* config/tc-ppc.c (ppc_force_relocation): Add all relocs that
expect a symbol in md_apply_fix. Remove tls pcrel relocs
already covered in general tls match range.
(cherry picked from commit 8b168f1a1e09e337d2a970f204a0230c091bbe58)
