I've noticed another issue with x86 testing: both on Solaris/x86
(i386-pc-solaris2.11) and Linux/x86 (i686-unknown-linux-gnu), many tests
fail for the 64-bit multilib:
FAIL: libffi.call/closure_simple.c -W -Wall -Wno-psabi -O0
-DABI_NUM=FFI_STDCALL -DABI_ATTR=__STDCALL__ (test for excess errors)

The 32-bit x86 test in libffi.exp is bogus. The following patch fixes
this, tested with the appropriate runtest invocation on
i386-pc-solaris2.11. Ok for mainline?
