Fixincludes echoes several $1's instead of $1's value.

I have made fixincludes try $1 and $libdir/gcc-include before using
/usr/local/lib/gcc-include, and inserted an 'includes:' target in the
Makefile.

On Ultrix, /bin/sh -ec 'if false ....' aborts because the "false" in
	the if test is taken to be an error.  Replaced
	'if ...; then false; else ....; fi' in Makefile with
	'if !...; then ....; else false; fi'.
