I do something similar (I just keep copies of changed files around) but
if you modify a makefile and the program you are trying to prevent being
built gets moved then the other makefile builds it.  This is what happened
to me.  Besides, the fewer local changes I have, the better I like it.
I figure that local changes are for temporary fixes while a PR is in
the pipe and for local changes that no one else would ever want to
include.  This seems to have some marginal utility for more than just me.
