Right.

Take a look at config/lib-link.m4 and config/lib-prefix.m4. Then
compare to --with-mpfr and --with-mpfr-lib in the top level
configure.ac. Notice that they're about a hundredth of the size.
The top level also chose to use multiple options so maybe that's
wise after all. But anyway that lets us have --with-python-lib
and --with-python-include, avoiding the version-specific options.

The versions in config handle all sorts of complicated extra
scenarios. But they're pretty rare and there's others that aren't
handled. One which adds -L${withval}/lib and -I${withval}/include
works 99% of the time, and the user can fiddle CFLAGS/LDFLAGS for
the other cases.

I may rip out the existing uses, though we'll have to keep the long
option names for compatibility.

Thanks!
