[Bug java/20495] New: [4.0 Regression] building gcj hangs on gcj-dbtool

["mmazur at kernel dot pl" <gcc-bugzilla at gcc dot gnu dot org>]

Gcj is built with --enable-gtk-cairo --enable-libgcj-multifile --enable-libgcj-database. While 
building: 
 
creating gcj-dbtool 
./gcj-dbtool -n classmap.db || touch classmap.db 
 
And it hangs. Strace tells me: 
 
$ strace -p 23159 
Process 23159 attached - interrupt to quit 
futex(0x20001921b00, FUTEX_WAIT, 1, NULL <unfinished ...> 
 
And here's gdb:
