Log:
mips trampoline: don't bother with unwind tables
The utility here seems somewhat limited, but clang will attempt to generate
.eh_frame and actively fail in doing so. It is perhaps worth investigating
why it's being generated in the first place (GCC doesn't do so), but this
isn't a high priority.
