Bug#1112684: ioquake3 FTCBFS: debian/rules invokes build architecture build tools

Hi,

ioquake3 started to fail to cross build from source. The root cause is 
to be found in debian/rules where $(CC) defaults to cc and pkg-config is 
hard coded. I suggest including dpkg's buildtools.mk and using 
$(PKG_CONFIG) to use triplet-prefixed build tools. Once doing so, 
ioquake3 cross builds again. I'm attaching a patch for your convenience.

Helmut
