[PATCH] D40826: [LLD] Use Rela on PowerPC too

[Nicholas Allegra via Phabricator via llvm-commits]

comex created this revision.
Herald added subscribers: nemanjai, emaste.

The spec for ELF on PowerPC:
http://refspecs.linux-foundation.org/elf/elfspec_ppc.pdf
says:
"The PowerPC family uses only the Elf32_Rela relocation entries with explicit addends."

(EM_PPC64 should be covered by Config->Is64 already.)
