# WARNING!
# Although invoking the all, archive targets in this Makefile from a Yocto-like
# environment may succeed, you will end up with N different libraries that are
# actually being built using the same compiler flags, i.e. the CFLAGS from the
# environment. That is because Yocto builds the fm-lib for various platforms
# one at a time, by invoking only the corresponding libfm-<arch>.a, then
# install-<arch> targets for each platform that it's currently configured for.
# Set this as appropriate for local builds
CROSS_COMPILE?=aarch64-linux-gnu-
# You must set KERNEL_SRC or the <DESTDIR, PREFIX> pair
# before invoking this Makefile as standalone
KERNEL_SRC?=$(DESTDIR)$(PREFIX)
# These should be inherited from the environment with which Yocto invokes us,
# but in case not, then here we're making sure that we're actually using
# the cross-tools, and NOT the native ones:
