[Bug target/39472] Add -mabi=[ms|sysv]

Is it really so hard to change UEFI apps?
The thing is that by adding the -mabi= option you pessimize x86_64 gcc even
more than the attribute patches have done.  Now at least DEFAULT_ABI ==
SYSV_ABI
or DEFAULT_ABI != SYSV_ABI can be optimized into a constant at compile time,
with your patch it can't.
