This is a revert of a Debian-specific patch,
debian/patches/debian/61_glib-compile-binaries-path.patch.

I think it's probably OK to drop that patch, because libglib2.0-dev already
Depends on libglib2.0-bin, which ships the necessary symlink
/usr/bin/glib-compile-schemas -> ../lib/${MULTIARCH}/glib-2.0/glib-compile-schemas.

However, I am certainly not going to upload anything non-critical until
we get 2.66.6-1 into testing, and we're getting very close to the freeze.
How urgent is this change?
