The GLU check should already check for the math library; AFAICT, the
problem was that the libMesaGLw[M] check didn't check for GLU. NB:
This only applies to Mesa's libMesaGLw[M] from widgets-mesa; Mesa's
SGI-compatible version (in widgets-sgi) and the original SGI version
don't need GLU or the math library.
OTOH, none of the standard modules use libGLw, so omitting --with-glw
should be harmless.

Even so, it should be added. However, it probably isn't specific to
MySQL (if that's the only case which causes problems, it's probably
because it's a static library; linking against a shared library
normally links its dependencies automatically).
Which symbols are required from this library?

Awkward; curses may be overkill, as readline only actually needs the
termcap functions (tgetent etc). Ideally we should try libtermcap or
libtinfo before curses, but whichever library we choose, there's
always the possibility that it will turn out to be the wrong one for

I have no idea about this one. So don't use --with-readline (it's only
used by r.mapcalc).
