I've been trying to build the openmpi 1.2 branch with the Intel and
Portland Fortran compilers and was having trouble using their
-i-static/-Bstatic_pgi options.

First off, it seems the only way to get these options to appear in the
necessary link lines is to add them to the compiler variable itself, e.g.:

FC="ifort -i-static"

However, this causes problems with some configure checks in setting the
OMPI_F90_ABSOLUTE and similar variables, because "which" complains about
the extra arguments. I ended up making the following change:

which works for a single extra argument because basename doesn't
complain. However, basename does complain if you give it more
arguments. Something more general might be:

BASEF90=`echo $FC | sed 's/ .*//'`
BASEF90="`basename $BASEF90`"
OMPI_F90_ABSOLUTE="`which $BASEF90`"

I'm not sure what the most cross platform way to return only the first
argument is.

Of course, if there was a way to get these passed to the appropriate
link stages, we could avoid this. But it looks like libtool strips the
-i-static argument and doesn't pass it on to the link command, not sure
about the -Bstatic_pgi argument.
