Until now users would have to cargo cult or inspect the private
%default-modules variable of (guix build-systems gnu) to discover which
modules to include when extending the used modules via the #:modules argument.
The renaming was automated via the command:
$ git grep -l %gnu-build-system-modules
| xargs sed 's/%gnu-build-system-modules/%default-gnu-imported-modules/' -i
* guix/build-system/gnu.scm (%gnu-build-system-modules): Rename to...
(%default-gnu-imported-modules): ... this.
(%default-modules): Rename to...
(%default-gnu-modules): ... this. Export.
(dist-package, gnu-build, gnu-cross-build): Adjust accordingly.

;; Standard build procedure for Perl packages using the "makefile

;; maker"---i.e., "perl Makefile.PL". This is implemented as an extension of
|
|
;; `gnu-build-system'. Cross-compilation is supported for some simple Perl
|
|
;; packages, but not for any Perl packages that do things like XS (Perl's FFI),
|
|
;; which makes C-style shared libraries, as it is currently not known how to
|
|
;; tell Perl to properly cross-compile.
