The testcase gcc.target/mips/msa.c gives dozens of FAILs if it's tested
with a GCC configured to default to -fno-common, because of patterns like
/* { dg-final { scan-assembler-times "\t.comm\tv16i8_\\d+,16,16" 3 } } */
Seems like the simplest solution is to force -fcommon for this test. OK?

* gcc.target/mips/msa.c: Add -fcommon to dg-options.
