Drop the build-dep on openmpi-gcc.

You must make sure that the first build dependency in a set of
alternative build-deps is always installable, otherwise it's going to
FTBFS on the buildds (even if it builds fine for you locally). This
isn't an arch-specific problem if that's what you're concerned about;
if you had uploaded source+i386 (instead of amd64) packages, the amd64
build would have failed on the buildds instead.
