Without this patch, links using the $FCLIBS set by AC_FC_LIBRARY_LDFLAGS
will fail when the user has enabled inter procedural analysis with the
XL Fortran compiler; tested on BlueGene.
I'm not aware of any libink that might be relevant in the area of
compiler support libraries, but you never know, of course.
Thanks,
Ralf
Fix AC_FC_LIBRARY_LDFLAGS detection for BlueGene xlf -qipa.
* lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore
'-link', added spuriously when -qipa is used with the XL
Fortran compilers on BlueGene.
