Bug#814125: drumgizmo: FTBFS on non-Linux: automatic GUI detection broken

[Aaron M. Ucko]

Source: drumgizmo
Version: 0.9.8.1-1
Severity: important
Justification: fails to build from source

Builds of drumgizmo for non-Linux architectures (just kFreeBSD so far)
have been failing:

  Auto setting gui based on host: kfreebsd-gnu
  configure: error: Your platform is not currently supported

Please try explicitly passing --enable-gui=x11.  (It looks like the
upstream configure script inappropriately capitalizes BSD on line 46,
and doesn't attempt to cover the Hurd at all.)

Thanks!
