Add %M spec string token
In the GCC FAQ under "Dynamic linker is unable to find GCC libraries", one
suggestion is to add '-R' or '-rpath' linker option to the *link or *lib specs
so that the GCC libraries can be found.
E.G. the following line is added to the DRIVER_DEFINES when building gcc
via pkgsrc ('$(LINKER_RPATH_FLAG)' comes from the environment):
-DLINK_LIBGCC_SPEC="\"%D $(LINKER_RPATH_FLAG)$(libdir) \""
This is needed as the prefix is normally something like '/usr/pkg/gcc47'.
The problem is that this does not allow for multilib os directory's and
there is currently no simple way of dong so.
My solution is to add the '%M' token that expands to multilib_os_dir.
The above line can then be easily change to handle multilib directory's:
-DLINK_LIBGCC_SPEC="\"%D $(LINKER_RPATH_FLAG)$(libdir)/%M \""
