What's wrong with

  GZIP_PROG='' make install ...

?  This way, you don't need to decide up front whether you will or
will not want to compress, you decide at "make install" time.

If you want to disable compression of Lisp files, but leave alone the
compression of Info files, then I think it is much better to introduce
GZIP_LISP in the top-level Makefile.in without adding anything to the
configure script.  Again, the advantage is that no decision need be
made at configure time.
