Bug#911163: cmus FTCBFS: configures for the build architecture

[Helmut Grohne]

Source: cmus
Version: 2.7.1+git20160225-2
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

cmus fails to cross build from source, because it configures for the
wrong architecture. The configure script advises that one should export
CROSS for cross compilation. Additionally, PKG_CONFIG is needed on
Debian. The attached patch implements that and makes cmus cross
buildable. Please consider applying it.
