This provides a spec to insert "-rpath DDD" for each DDD corresponding
to a compiler startfile directory. This allows a target to use @rpath
as the install path for libraries, and have the compiler provide the
necessary rpath to handle this.
gcc/ChangeLog:
* gcc.c (RUNPATH_OPTION): New.
(do_spec_1): Provide '%P' as a spec to insert rpaths for
each compiler startfile path.
