RFA: fixlet in elfxx-mips.c

[Tom Tromey]

I'm using x86 F8.  The gcc on this system is based on 4.1.2.

When I build gdb with --enable-targets=all, the build fails in bfd.
On this platform, the 'sec' parameter to mips16_stub_symndx is unused
(due to how the macros expand on this host).  Since the build is done
with -Werror, this causes a failure.

This patch fixes the problem by marking the argument unused.

Ok?
