Problem with tabs in .mk file corrected in dir-locals.el

Previously we had tried to corrected the problem that `.mk' files use space
instead of TAB by setting them to be read into makefile-mode at the
start. However, for some reason, this caused a problem in reading the
maximum line length (the value of 75 wasn't read by Emacs).

So after some playing around, I found out that the problem is that the
`nil' setting (for all other files) must be defined in the end, not the
start of the basic settings and this solved this problem.
