Some kind of race condition seems to occur on my system, and builds are run to link against image/lib64 before libs are actually put in place when building with MAKEOPTS="-j2"...
libieee1284 appears to be a parallel port library, but is a dependency of emul-linux-x86-medialibs, therefore emul-linux-x86-soundlibs, therefore emul-linux-x86-qtlibs, therefore things like the good old 32-bit-only skype.
At least until Qt gets some proper multilib support.
Marked as major for that reason, feel free to kick me in the stomach and down it.
