I've reached my limit in multiple linking on Mac OS X

So a side-effect of OSX's crappy linker is that when you have a
library specified multiple times on the command-line (-lkdecore
-lkdecore) it actually tries to mmap them twice when linking, even
though the resulting binary only has one link (as it should).

I'm hitting an issue now where it's impossible to link
libkmailprivate, even with the tricky KDEPIM4_LINK_UNIQUE_LIBRARIES
macro which deduplicates anything specified in a TARGET_LINK_LIBRARIES
command:

The cmake macro is this:

kdepim4_link_unique_libraries(kmailprivate ${KDE4_KHTML_LIBRARY}
${KDE4_THREADWEAVER_LIBRARY} ${KDE4_KMIME_LIBRARY}
${KDE4_KPIMIDENTITIES_LIBRARY} ${KDE4_PHONON_LIBRARY}
${KDE4_KNOTIFYCONFIG_LIBRARY} ${KDE4_KTNEF_LIBRARY}
${KDE4_KUTILS_LIBRARY} ${KDE4_MAILTRANSPORT_LIBRARY}
${KDE4_KIMAP_LIBRARY} kleo ${QGPGME_LIBRARY} mimelib ksieve kpgp
kdepim ${QT_QT3SUPPORT_LIBRARY})

You'll notice that basically everything is already using *_LIBRARY
instead of the normal _LIBRARIES stuff and it's still not enough.
There are a bunch of -lkdecore references, -lkdeui references, etc.

Is there any solution other than making a patch to deduplicate the
linker line at the cmake level?  Right now kdepim is unlinkable on Mac
OS X, and it will only get worse if more dependencies are added.
