OK - we need to figure out what's different in the setups (I don't get the same
result)
-----
* I found that there was one incorrect case in libgfortran (where there is a
direct reference to **environ from the dylib, which is not allowed) - this was
being hidden by the 'global dynamic_lookup' -- the master-wip-config-darwin20
branch has a patch now for that too.
My test setup
clean install of macOS11.0.1
master-wip-config-darwin20
command line install of XC12.2RC
GMP/MPFR/PMC/ISL are built in-tree (the sources are symlinked into the root
dir)

^^^ My bootstrap compiler is x86_64-apple-darwin19 gcc-7.5 (with Ada because of
enable-languages=all)
I have build logs, install logs and test logs, none of these are showing any
error.

====
The effort of testing a top-level configuration change across multiple
platforms is quite significant - so I'd rather not hack a minimal change and
then have to go back and fix it properly later - so let's get to the bottom of
what's happening and find the correct solution.
