This test FAILs on i686-linux:
FAIL: gcc.dg/pr92768.c (test for excess errors)
Excess errors:
/home/jakub/src/gcc/gcc/testsuite/gcc.dg/pr92768.c:4:1: warning: SSE vector
return without SSE enabled changes the ABI [-Wpsabi]
Similarly to other tests, I've added -w -Wno-psabi to disable such warnings,
different targets have different and not all have it under -Wno-psabi.
Tested on x86_64-linux and i686-linux, committed to trunk as obvious:

* gcc.dg/pr92768.c: Add -w -Wno-psabi to dg-options.
