Makefile: remove --no-print-directory

1 The comment before MAKEFLAGS assignment (see commit 25e8cb5c) talks
about -r (and possibly -R) flags and has nothing to do with
--no-print-directory. Let's remove the last option to not confuse
a reader.

2 The --no-print-directory flag to build and build-crtools shorthands
is redundant, because scripts/Makefile.build has it already. Remove.
