-12 fails to build

[Ari Pollak <aripollak@gmail.com>]

I don't know if anyone's noticed yet since I haven't seen any commits or 
messages about it on the mailing lists, but xfree86 4.3.0.dfsg.1-12 is 
failing to build on all architectures: 
http://buildd.debian.org/fetch.php?&pkg=xfree86&ver=4.3.0.dfsg.1-12&arch=i386&stamp=1108799673&file=log&as=raw
