Currently, when installing two versions/copies of GCC into the same prefix,
using suitable --libdir, --infodir and --program-suffix options, the *only*
conflict, that is, the only file the second copy of GCC will overwrite, is
lib/pkgconfig/libgcj.pc.
One approach would be putting this into a version-specific subdirecty, such
as --libdir, or name the file libgcj41.pc, libgcj42.pc, etc.
