A few symbols are missing in n32 and are there in n64.  Is that 
intentional?  I'd like to defer review for 12-15 to someone who can test 
this out.

The symbol difference is because I pushed some patched for the libpthread 
removal project that removed some libpthread.abilist entries.  But this
patch is quite mechanical and it easily verified with a check-abi, so
the rebase should be simple:

$ cp sysdeps/unix/sysv/linux/mips/mips64/libpthread.abilist sysdeps/unix/sysv/linux/mips/mips64/n32/libpthread.abilist
$ cp sysdeps/unix/sysv/linux/mips/mips64/libpthread.abilist sysdeps/unix/sysv/linux/mips/mips64/n64/libpthread.abilist

And run a check-abi for mips64-linux-gnu and mips64-n32-linux-gnu.

Same for patches 12-15, the tests should be to just simple ran
make check-abi against the affected ABIs.
