I tried this (patch below), but libtool doesn't seem to do the right thing:

$ readelf -d ~/gcc3/lib/libgcj.so

Dynamic segment at offset 0x3ee284 contains 23 entries:
  Tag        Type                         Name/Value
 0x00000001 (NEEDED)                     Shared library: [libpthread.so.0]
 0x00000001 (NEEDED)                     Shared library: [libdl.so.2]
 0x00000001 (NEEDED)                     Shared library: [libgcc_s.so.0]
 0x00000001 (NEEDED)                     Shared library: [libc.so.6]
 0x0000000e (SONAME)                     Library soname: [libgcj-3.0.so.2]
[...]

The "-3.0" is built in to the soname, which is not what we want because this will
mean that every change in the release number breaks compatibility. How can we make
it use "libgcj.so.2" for the soname, and make a libgcj.so.2 -> libgcj-3.0.so
symlink?
