libtool using -rpath on Darwin

[Hauke Fath <hauke%Espresso.Rhein-Neckar.DE@localhost>]

Hi,

building graphics/jbigkit on MacOS X Tiger / Darwin 8 fails with

[...]
gmake[1]: Entering directory 
'/opt/local/obj/graphics/jbigkit/work/jbigkit-2.1/pbmtools'

even though mk/platform/Darwin.mk tries to discourage sending GNU ld 
specific options to the system linker.

The jbigkit build system is heavily patched to use libtool on every 
corner. What does it miss on Darwin?

Cheerio,
Hauke
