Avoid ordered comparison of pointer with integer to prevent compile error
with GCC 11.

Reported by Julien Lepiller &lt;julien@lepiller.eu&gt;.

This reduces peak memory consumption to something less unreasonable.

* Makefile.am (make-go): Depend on 'make-*-go' targets; remove body.
(guile-compilation-rule): New function.
(MODULES_CORE, MODULES_PACKAGES, MODULES_SYSTEM, MODULES_CLI): New
variables.
&lt;top level&gt;: Call 'guile-compilation-rule' 4 times.
* build-aux/compile-all.scm &lt;top level&gt;: Expect "--total" and
"--processed".  Take them into account when displaying progress
reports.
