Bug#673839: Building an udeb binary

[Sebastien Bacher <seb128@ubuntu.com>]

Package: libxdamage
Version: 1:1.1.3-2

Currently gtk is doing a second build pass with different configure 
option for its udeb flavor because libxrandr, libxcomposite and 
libxdamage don't have udebs. It would be nice if you could add an udeb 
to libxrandr so we could bring gtk into a single pass build

Thanks,
