Several sub-directories of the gcc code base are in fact not needed for the Buildroot build: libjava/, libgo/ and gcc/testsuite/ being the biggest ones. Avoiding their extraction saves quite a bit of disk space, and compensates a bit the fact that we now extract three times the gcc source code. This requires changing the 100-uclibc-conf.patch to no longer patch files from the libjava/ directory, since this directory is no longer extracted.
