Richard, can you help?

It took me a little while to set it up, but I have now did this testing.
I ran o32 testing only, for standard MIPS, MIPS16 and microMIPS code (GCC
multilibs). I had to tweak compiler options used in testing so as to
avoid producing code incompatible with standard MIPS PLT entries,
`-fno-optimize-sibling-calls' and `-mno-jals -fno-optimize-sibling-calls'
respectively for MIPS16 and microMIPS code. Standard MIPS code required
no extra options. There were no regressions in this setup with binutils
2.23 (the tip of binutils-2_23-branch).
