Simple patch to give bin/jt9 an executable stack

gfortran puts trampolines on the stack and marks decoder.f90.o as needing an
executable stack, but the linker on FreeBSD ignores this and make the stack=
 NX.

I've done two different patches depending on the maintainers appetite for
maintaining them.  The first simply marks jt9 as needing an executable stac=
k,
and the second uses mprotect() to dynamically mark the trampolines RX then =
set
back to RW after the call.
