This change allows the test to pass. The failure of 
gcc.target/i386/funcspec-5.c is

/opt/gcc/work/gcc/testsuite/gcc.target/i386/funcspec-5.c:34:1: warning: SSE 
instruction set disabled, using 387 arithmetics [enabled by default]
 extern void test_no_sse (void)   __attribute__((__target__("no-sse")));

This extra warning is silenced by dg-options "-mno-sse", but not by 
"-mno-sse4.2".
