I am running NPTL libpthread, whose call sites were fixed a while back
in commit 9a4c8a3f2 (mips: fix errno setting after syscall).

I did not see any __syscall_error() calls in linuxthreads.old .  I did
grep for all __syscall_error() callers on MIPS, to ensure that all of
them were using $a0 now.

Normally __syscall_error() isn't called explicitly from
librt/libpthread/etc. except for special cases; instead, it is called
from a wrapper like PSEUDO.  The wrappers were already in good shape,
but my first patch was required to fix up some of the special cases.
