Paolo Bonzini 036999e93e optionrom: fix detection of -Wa,-32
The cc-option macro runs $(CC) in -S mode (generate assembly) to avoid a
pointless run of the assembler.  However, this does not work when you want
to detect support for cc->as option passthrough.  clang ignores -Wa unless
-c is provided, and exits successfully even if the -Wa,-32 option is not
supported.
