Pushing this obvious followup to fix the test on some systems.
Only OpenMP related failures I'm still seeing are with the plain
`AC_OPENMP' test: Solaris 2.6 cc may dump core at some point during
configure, and IRIX cc may create a directory rii_files, both of which
upset the leftover file checks.  I'm not sure when it is suitable to
remove rii_files, though.

Cheers,
Ralf

    Do not fail OpenMP tests on systems without aclocal.
    
    * tests/c.at (AC_OPENMP and C, AC_OPENMP and C++): Override
    `ACLOCAL=true' for autoreconf, the tests don't need aclocal.
    * tests/fortran.at (AC_OPENMP and Fortran 77)
    (AC_OPENMP and Fortran): Likewise.
