Disable linker warnings on MIPS builds to work around relocation issue.

Bug: 14296739

Clang is emitting a text relocation for __gxx_personality_v0 on MIPS, and
the linker is treating this as an error (converted from a warning initially).
The warning appears harmless in this case, so the temporary solution is to
disable it until the LLVM bug is fixed.
