I'd suggest using

  -qextname

option for xlf. It is safer to have Fortran names ended with _ in
order to avoid possible name conflicts.

Another (but only if necessary, e.g. when using system Fortran
libraries that were compiled without -qextname) option would be to use

  python setup.py build_ext -DNO_APPEND_FORTRAN build

for building scipy.
