[Debian-med-packaging] Bug#1126383: libsort-key-top-perl FTCBFS: uses the build architecture compiler as linker

[Helmut Grohne]

Source: libsort-key-top-perl
Version: 0.08-5
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

libsort-key-top-perl fails to cross build from source, because it uses
the build architecture compiler as linker. It originates from
debian/rules passing LD. The value is looked up from Perl's sysconfig
data without considering the host architecture. I propose using dpkg's
buildtools.mk as source instead. Once doing so, it cross builds
successfully. I'm attaching a patch for your convenience.
