Thank you. I really like that contrib/download_prerequisites script.
All this time, I had never known it would pick up the simple names in
the top directory. I changed the version numbers to the current set and
it worked like a charm. The --enable-fixed-point threw some "could not
emulate" errors but folks are waiting on me. So I just ditched the
switch. It has been rolling along ever since. Thanks again.

I built the GMP, MPFR, MPC and ISL out of the Infrastructure directories

In this case, stage1-gcc is linked to shared objects in
/N/soft/rhel7/gcc/infrastructure/lib.

**************************
You should add /N/soft/rhel7/gcc/infrastructure/lib into shared object
searching path of ld.so(8). You can use LD_LIBRARY_PATH or ld.so.conf
to do this.
If you don't want to deal with shared object dependencies, you should
put MPC, MPFR, GMP, and ISL into GCC source tree. The script
contrib/download_prerequisites in GCC source tree would do that.
