If libgcj isn't compiled with -Bsymbolic, won't it still be possible for 
a libgcj symbol to resolve to another shared object, if the other shared 
object contains symbols that conflict? My understanding of -Bsymbolic is 
that it will resolve symbols internally where possible, but they will 
still be exported and thus valid link targets from other .so's.
