There are several modula-2 issues on Darwin, some blocking bootstrap on
one or more system versions.
This has been tested on powerpc/i688-darwin9 .. x86_64-darwin10,17,21 and
the prototype aarch64-darwin branch on darwin21.
OK for trunk?
thanks

NOTE: As discussed in the PR, there are likely to be other changes to the
_definitions_ of the module registration constructors. This patch only
relates to the _references_ to those CTORs.
--- 8< ---
The symbols for module registration constructors need to be external
or we get wrong code generated for targets that allow direct access to
local symbol definitions.
