perlPackages: Add cross-compilation support. This involved: * Installing miniperl as $dev/bin/perl * Setting miniperl to take INC from lib/perl5/{site_perl/,}cross_perl/${version} as well as lib/perl5/{site_perl/,}/${version}/${runtimeArch}, in that order. miniperl taking from runtimeArch is not really correct, but it works in some pure-perl cases (e.g. Config.pm) and can be overridden with the cross_perl variant. * Installing perl-cross's stubs into $dev/lib/perl5/cross_perl/${version} * Patching MakeMaker.pm to gracefully degrade (very slightly) if B.pm can't be loaded, which it can't in cross-compilation. * Passing the right build-time and runtime perls to Makefile.PL

# Adding the arch-specific directory is morally incorrect, as
# miniperl can't load the native modules there. However, it can
# (and sometimes needs to) load and run some of the pure perl
# code there, so we add it anyway. When needed, stubs can be put
# into $1/lib/perl5/site_perl/cross_perl/@version@
