Darwin: Recognise -weak_framework in the driver [PR116237].
XCode compilers recognise the weak_framework linker option in the driver
and forward it. This patch makes GCC adopt the same behaviour.
PR target/116237
gcc/ChangeLog:
* config/darwin.h (SUBTARGET_DRIVER_SELF_SPECS): Add a spec for
weak_framework.
* config/darwin.opt: Handle weak_framework driver option.
