Richard Henderson showed that the libjava build spends 2/3 of its time
in libtool, and that his hand-hacked (but not portable) modification to
invoke the appropriate binutils commands directly gave a huge speedup.
To me, 300% overhead means major breakage, so we need a better libtool.
However, this better libtool might not yet exist.
