Currently LLD will not convert the encoding. This change allows me to build and link MIPS64 FreeBSD using clang+lld without having to fix up things in the linker.
I think this is a much simpler approach than making LLD reassemble the eh_frame with relative values.

ld.bfd also accepts these clang generated input files and generates the same eh_frame output as lld.

We could still add the eh_frame rewriting support in the future.
