  The current setup leads to spurious test fails, where we are building for
macOS 10.4 or earlier.

Tested on x86_64, i868, powerpc Darwin, x86_64 Linux, pushed to trunk,
thanks
Iain

When we have @rpath support by virtue of the OS version we're hosting on
we still need to omit those rpath entries when targeting < 10.5 (or the
linker will complain).  To do this we (maybe ab-)use a property of the
spec function expansion that a non-null return value can be used as the
true input to a second spec (whereas, unfortunately, we cannot pass specs
to the version function at present).

gcc/ChangeLog:

	* config/darwin.h (DARWIN_RPATH_SPEC): Arrange for the %P spec
	to be conditional on macosx-version-min.
