Bug#1069921: libusb-java FTCBFS: uses the build architecture compiler

[Helmut Grohne]

Source: libusb-java
Version: 0.8+ztex20090101-9
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

libusb-java fails to cross build from source, because the upstream
Makefile uses a non-standard variable (GCC) for the C compiler and
because debian/rules does not pass cross tools to make. I propose
renaming the variable to the usual CC variable and using dh_auto_build.
Please find a patch attached.

Helmut
