Unconditionally compile romstage with -Wa,--divide

The option --divide is required by our assembler to ensure that
    '/' is not parsed as a comment sign but as a division, because
    some of the cache as ram code is using divisions.

The --divide parameter has been part of the GNU as since binutils 2.17.
    Hence, compile romstage (which contains cache as ram init) with
    -Wa,--divide unconditionally instead of probing for it and adding it to
    all compiler invocations (because that is causing random trouble with
    clang when compiling the SMM code and calling gcc with --divide instead of
    -Wa,--divide)
