  [Driver] -fno-plt: warn for unsupported targets

-fno-plt is an ELF specific option that is only implemented for x86 (for
a long time) and AArch64 (#78890). GCC doesn't bother to give a
diagnostic on Windows. -fno-plt is somewhat popular and we've been
ignoring it for unsupported targets for a while, so just report a
warning for unsupported targets.
