 The upshot is that Octave needs to depend explicitly on the minor version
 number of gcc so that octave gets rebuilt when upgrading from gcc 5.3 to
 5.4, etc.  The reason is that mkoctfile depends on a directory that has
 the minor version in its name, and there seems to be no mechanism for
 generalizing this.  The symptom is that Octave's pkg command does not work
 for installing things like the control package from Octave forge.
