[Darwin, PPC] Allow the user to override the use of hard float in kexts.
The default for the kernel is soft-float, however a user writing a kernel
extension might want to make use of hard float. This change makes
" -mkernel -mhard-float " work as expected.

* config/rs6000/rs6000.c (darwin_rs6000_override_options): Honour
