Perhaps, but this is sounding like a red herring: the discussion was about
build times.

I tried a "rm -f && make" in my build tree.  Here are
the timings for a --disable-shared build:

88 seconds waiting for libtool to make up its mind
10 seconds for ar to create libgcj.a from 1754 object files
4 seconds for ranlib

It's pretty clear where the inefficiency lies.  If you could concoct a
portable Ant build file without libtool it'd likely be faster, but then
you could do the same with make.
