[PATCH][RFC] Param flags for testsuite

[Richard Guenther]

If you try to run the testsuite with an extra --param added, you figure
out that dejagnu doesn't like this.  The only way I got it work is to use

make check RUNTESTFLAGS="--target_board=unix/--param/max-aliased-vops=0"

but then dejagnu makes "--param -mmax-aliased-vops=0" out of that.  Fixed
by the following patch.

Ok?  Better ideas?

Thanks
Richard.

	* opts.c (handle_param): If the param name starts with '-m',
	skip that part.
