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.

;;
;; 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'.
;; `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.
