perl-cross-debian update

Long term maintenance of cross-build support for the Debian configuration of perl has now gained some code at github and an ITP: #694326 for Debian.

There's some working code for perl 5.14 and initial work on 5.16 (which isn't complete yet).

This will dramatically simplify the patch for #633884 and provide a base for getting another part of that patch into upstream (Makefile.SH). (Thanks to Steve McIntyre & Peter Pearse for the body of the patch itself.)

ifneq ($(DEB_HOST_GNU_TYPE),$(DEB_BUILD_GNU_TYPE))



define variant

$(if $(findstring static,$1),static,$(if $(findstring debug,$1),debug,shared))

endef



define cross-config

    /usr/bin/perl-cross-debian --variant $(call variant,$@)

    perl -Ilib  make_patchnum.pl

endef

endif

So the config*variant files will live in /usr/share/perl-cross-debian/$arch/$perl_version/
