  I assume Jim want to keep --disable-shared as a convenient way to
force libtool to generated binaries statically linked which is easier
when dealing with gdb. If that's the case what would be nice is to be
able to instruct auto*/libtool to build both libraries (where possible)
but force linking with static libraries. I have no idea how to do this
but that would be an useful option for autogen or configure.
  Or just disable python if --disable-shared is passed that would be
fine too I think,
