As of emacs-snapshot:

M-x compile
make -k <TAB>
no longer completes filenames.
Furthermore, more TABs will get you

Indeed, the completion rules for `make' failed to mention that file
names are perfectly valid arguments.  I've just installed the patch
below which should address this problem.

I can't reproduce this problem.  Can you give more detailed steps to
reproduce it?

Easy as cake.
$ set emacs-snapshot
$ apt-cache policy $@
emacs-snapshot:
  Installed: 1:20111206-1 # How can I give you a more exact version ? BUG !
$ mkdir v
$ cd v #no files here
$ emacs -Q -nw -f compile
TAB

OK, I can reproduce it now and I have a fix for it.  But I have one
question: you originally said you wanted to complete on filenames, but
this bug shows up when there's no Makefile, in which case you'd first
want to specify a file via -f, right?

Yes, tons of possibilities... and I hit TAB by accident and discovered
the bug.
