tools/nolibc: fix the makefile to also work as "make -C tools ..."
As reported by Linus, the nolibc's makefile is currently broken when invoked as per the documented method (make -C tools nolibc_<target>), because it now relies on the ARCH and OUTPUT variables that are not set in this case. This patch addresses this by sourcing subarch.include, and by presetting OUTPUT to the current directory if not set. This is sufficient to make the commands work both as a standalone target and as a tools/ sub-target. Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
