[OMPI users] OpenMPI and pgf90 -- adding flags to mpif90 compile

[Cable, Sam B Civ USAF AFMC AFRL/RVBXI]

I need to build OpenMPI with Portland Group Fortran.  I need to add a
flag to the pgf90 linker command that is run when mpif90 is invoked.  I
have tried configuring with LDFLAGS and -with-wrapper-ldflags, but
nothing works.  I am thinking that surely there is a way to get
non-default flags put into the pgf90 command, but I am out of options,
as far as I can tell.  Anyone know how to do this?  Thanks.
