Looks like we might have an automagic dependency on media-sound/jack-audio-connection-kit, which triggers a failure if media-sound/jack-audio-connection-kit[abi_x86_32] is not installed.
The Jack dependency needs to be there for gcj builds or --disable-dssi needs to be passed to configure. $ ./configure --help|grep dssi --disable-dssi compile DSSI providers (enable by --enable-dssi) $ grep -r 'jack' `find -name 'Makefile.am'` ./native/jni/midi-dssi/Makefile.am:libgjsmdssi_la_LIBADD = $(top_builddir)/native/jni/classpath/jcl.lo -ljack
configure does check for jack/jack.h but not the library, which explains why it's failing on multilib.
