ompi_setup_f77.m4 should allow for more than one word in $F77.
Autoconf typically uses something like this to extract the first word:
# Extract the first word of "$ac_prog", so it can be a program name with args.
set dummy $ac_prog; ac_word=$2
so OpenMPI could use that, too (with variable names changed, of
course, so they don't interfere with Autoconf's),

Yes, this is a problem. On the libtool command lines, you can use
to get -i-static passed to the compiler driver; and
to get it passed to the linker directly (but that would be wrong in this
case). Unfortunately, you may not in general be able to stuff this in
LDFLAGS at configure time (I haven't tried, it may just happen to work),
so one different way would be to stick it in at make time only:
But then, configuring with
> FC="ifort -i-static"
is a much better option: it tests the right setting at configure time.
Note there may still be issues: libtool should actually be able to
understand what -i-static really means (and for example not worry about
those libraries that are linked statically). But the FC setting should
get you going.
Hope that helps.
