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.
