Configuration: portability fixes in Less and WCSLIB
SUMMARY: no change is necessary in your project, unless you use the Fortran
features of WCSLIB in your project.

Until now, there were two compilation failures on recent macOS computers
with an M1 CPU: Less would crash because it couldn't find the relevant PCRE
(perl-compatible regular expression) libraries and WCSLIB would crash
because the LLVM compiler's Fortran features could not be built.

With this commit, both issues have been fixed by disabling the relevant
feature. Extensive comments have been placed in both places in case your
project needs these features, so please see the comments in the relevant
part of 'reproduce/software/make/basic.mk' for Less and
'reproduce/software/make/high-level.mk' for WCSLIB. In fact the previous
solution (where we would not have Fortran features in WCSLIB on macOS
systems was problematic and non-reproducibile (the features of WCSLIB
depended on the operating system!).

Another minor change was that for macOS, we now directly use the
version-string of WCSLIB to fix the internal linking issue there. As a
result, WCSLIB is no longer a "Version-dependent build" software (in
'reproduce/software/config/versions.conf'). Recall that these are software
that when changing the version, it is also necessary to inspect their build
recipe.

These two issues and their fix were discovered and fixed with the help of
James Robinson.
