build: don't tell "make clean" to remove my '~' backup files

build: don't tell "make clean" to remove my '~' backup files

Hi Rich,

automake's policy on what to remove via "make clean" is reasonable:
if running build rules creates it, then "make clean" can and should remove it.
However, even if build rules happen
to create backup files, please remove only the specific ones
they can create, not all of the ones in a directory.  Just in case
someone relies on those and expect them to hang around...
