Actually, KDE itself turned off -as-needed by default shortly before KDE 3.4 
was branched, since it was causing too many funky problems, so the extra 
CONFIGURE_ARGS in bsd.kde.mk is mostly a no-op (except for programs which 
ship with an admin-dir from KDE-HEAD on the road to 3.4).

We've put in an honest effort to get things to work with -as-needed during the 
the KDE 3.4 shakedown, but the long story short is that the feature is just 
too unreliable and causes too many problems. Libpthread also isn't the only 
library that ld manages to magically spirit away, it's just the most obvious 
showstopper for KDE.
