build-system/perl: Support cross-compilation of some Perl packages.
* guix/build-system/perl.scm: Add info on cross-compilation. (lower)[private-keywords]: Remove #:target when cross-compiling. (lower)[target]: Set. (host-inputs)[perl]: New entry. (host-inputs)[(standard-packages)]: Move to ... (build-inputs)[(standard-packages)]: ... here when cross-compiling. (build-inputs)[standard-cross-packages]: Add when cross-compiling. (target-inputs): New entry when cross-compiling. (build): Use perl-cross-build when cross-compiling. (perl-cross-build): New procedure. Signed-off-by: Mathieu Othacehe <othacehe@gnu.org>
