[PATCH] Add MIPS Linux support to gcc.misc-tests/linkage.c (testsuite/51748)

[apinski--- via Gcc-patches]

From: Andrew Pinski <apin...@marvell.com>

This adds MIPS Linux support to gcc.misc-tests/linkage.exp.  Basically
copying what was done for MIPS IRIX and changing the options to be correct.

OK?
