[Debian-on-mobile-maintainers] Bug#994671: axc FTCBFS: hard codes the build architecture compiler

[Helmut Grohne]

Source: axc
Version: 0.3.6-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

axc now cross builds successfully, but the resulting .deb is so broken
that we classify it as build failure. It uses build architecture
multiarch paths instead of host architecture ones. The reason is rooted
in gcc -print-multiarch, which prints the build architecture multiarch.
We need to use the host architecture multiarch there. Please consider
applying the attached patch.
