hmm i think it's been this way more or less forever ;). the libtool hack function that rewrites from the os multilib dir to the internal multilib dir just used $LIBPATH all the time instead of the specific sub-$LIBPATH dir. easy enough fix once identified: http://sources.gentoo.org/eclass/toolchain.eclass?r1=1.671&r2=1.672
