Aha!  That is exactly what I needed to do.  I made a specs file with

  *link:
  -bpT:0x10000000 -bpD:0x20000000 %{!r:-btextro} -bnodelcsect   %{static:-bnso %(link_syscalls) } %{shared:-bM:SRE %{!e:-bnoentry}}   %{!maix64:%{!shared:%{g*: %(link_libg) }}} %{maix64:-b64} %{mpe:-binitfini:poe_remote_main}

  *startfile:
  %{!shared:   %{mpe:%{pg:/usr/lib/gcrt0.o}         %{!pg:%{p:/usr/lib/mcrt0.o}               %{!p:/usr/lib/crt0.o}}}   %{!mpe:     %{maix64:%{pg:gcrt0_64%O%s}%{!pg:%{p:mcrt0_64%O%s}%{!p:crt0_64%O%s}}}     %{!maix64:       %{pthread:%{pg:gcrt0_r%O%s}%{!pg:%{p:mcrt0_r%O%s}%{!p:crt0_r%O%s}}}       %{!pthread:%{pg:gcrt0%O%s}%{!pg:%{p:mcrt0%O%s}%{!p:crt0%O%s}}}}}}

Now I can compile and link with -mpe and everything works fine.
Thanks a lot!

p.s. Fortran actually seems to work fine.  It is just that libf2c
isn't installed.
