Aspell 0.60.3 uses several math-related functions (log, sqrt, floor), but
doesn't check to see if an external library (e.g. libm) is required to
satisfy those symbols.  This results in undefined symbols when creating or
linking against the shared library.

The fix is easy -- have configure check to see if libm is needed to satisfy
any of these symbols:
