[bug #27609] Stupid inference rule for yacc files can clobber C sources!

[Kaz Kylheku]

Follow-up Comment #8, bug #27609 (project make):

I was just burned by this again! I have a small project with "hc.l" lexer, and
a "hc.c" source file.  It's been working fine. 

My Makefile was generating lex.yy.c from hc.l, compiling hc.c to hc.o, and
lex.yy.c to lex.yy.o, and linking everything.

All of a sudden though, for some reason, an internal rule in make kicked in
and did this:

   lex -t hc.l > hc.c

oops, my source file is gone; all I have is the most recent git repo copy
which doesn't have all my recent work.

Is this is another POSIX-required misfeature?

This is the sort of thing for which Stallman invented --posix-me-harder.
