Nick Alexander feb76eb004 Bug 1368699 - Pre: Remove MY_{CONFIG,RULES} Makefile customization hooks. r=gps
I very much doubt these are used, but even if we are -- we shouldn't
support this type of local customization, since it doesn't extend to
non-Make-based backends.

With the customization point removed, there's no way to set ETAGS, so
we remove what little support there was for generating Emacs tags.
