Andrew Turner d422e6f9b5 Add the start of libc and libstand for arm64. Not all of the machine 
dependent functions have been implemented, but this is enough for world.

Makefile
Raw Blame History

# $FreeBSD$
#
# Option file for FreeBSD /usr/src builds.
#
# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
# with sensible (usually) defaults.
#
# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
# are applicable for that Makefile (typically there are none, but sometimes there
# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
# to omit from that make.
#
# Makefiles must include bsd.mkopt.mk before they test the value of any MK_FOO
# variable.
#
# Makefiles may also assume that this file is included by src.opts.mk should it
# need variables defined there prior to the end of the Makefile where
# bsd.{subdir,lib.bin}.mk is traditionally included.
#
# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
# should be added. Old instances should be removed since they were just to
# bridge the gap between FreeBSD 4 and FreeBSD 5.
#
# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
# exception is made for _WITHOUT_SRCONF which turns off this mechanism
# completely inside bsd.*.mk files).
#

#
# Define MK_* variables (which are either "yes" or "no") for users
# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
# make(1) environment.
# These should be tested with `== "no"' or `!= "no"' in makefiles.
# The NO_* variables should only be set by makefiles for variables
# that haven't been converted over.
#
# These options are used by src the builds

# Default behaviour of some options depends on the architecture. Unfortunately
# this means that we have to test TARGET_ARCH (the buildworld case) as well
# as MACHINE_ARCH (the non-buildworld case). Normally TARGET_ARCH is not
# used at all in bsd.*.mk, but we have to make an exception here if we want
# to allow defaults for some things like clang to vary by target architecture.
# Additional, per-target behavior should be rarely added only after much
# gnashing of teeth and grinding of gears.
