Makefile: Don't create extraneous -.s file

Browse source 
In order to probe availability of certain features the Makefile test
compiles a handful of tiny snippets, feeding those in from stdin.  However
in one case - the one for -fstack-protector - it forgets to redirect the
output to stdout, meaning it creates a stray '-.s' file when make is
invoked (even make clean).
