build: Makefile splits Scheme compilation in four steps.
Fixes <https://bugs.gnu.org/48963>. Reported by Julien Lepiller <julien@lepiller.eu>. 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. <top level>: Call 'guile-compilation-rule' 4 times. * build-aux/compile-all.scm <top level>: Expect "--total" and "--processed". Take them into account when displaying progress reports.
