Thomas Weißschuh ae1f550efc tools/nolibc: add stdbool.h header

stdbool.h is very simple.
Provide an implementation for the user convenience.

Makefile for nolibc installation and tests

include ../../scripts/Makefile.include

we're in ".../tools/include/nolibc"

ifeq ($(srctree),) srctree := $(patsubst %/tools/include/,%,$(dir $(CURDIR))) endif

when run as make -C tools/ nolibc_ the arch is not set

ifeq ($(ARCH),) include $(srctree)/scripts/subarch.include ARCH = $(SUBARCH) endif

OUTPUT is only set when run from the main makefile, otherwise

it defaults to this nolibc directory.

OUTPUT ?= $(CURDIR)/

ifeq ($(V),1) Q= else Q=@ endif
