Bug#836544: libutempter FTCBFS: uses build architecture compiler

[Helmut Grohne <helmut@subdivi.de>]

Source: libutempter
Version: 1.1.6-3
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap

libutempter fails to cross build from source, because it uses the build
architecture compiler. The later dh_strip (which uses host architecture
tools) fails operating on the generated ELF objects. The attached patch
supplies a triplet-prefixed CC variable and allows overriding CC for use
with e.g. clang based builds. Please consider applying it.
