Simon J. Gerraty bee3d4bf8e Move DIRDEPS_BUILD settings to sys.dirdeps.mk
When originally implemented, there was no distinction between
DIRDEPS_BUILD and META_MODE, they were one and the same.

META_MODE however is useful by itself, but since meta.sys.mk
had lots of settings related to DIRDEPS_BUILD its use was limited
to DIRDEPS_BUILD.

Move (most) DIRDEPS_BUILD related items to sys.dirdeps.mk
so that meta.sys.mk can be used for just META_MODE.
There is of course some bluring of the lines, so settings remain
in meta.sys.mk

Add MK_META_ERROR_TARGET to enable the META_MODE .ERROR target
independent of DIRDEPS_BUILD, it copies failed .meta files to ${SB}/error
to make it easier to identify the cause of build failures.

Since sys.dirdeps.mk should be included first, most of
local.meta.sys.mk becomes local.sys.dirdeps.mk
and some other bits need to move to local.sys.dirdeps.env.mk

Also fix dirdeps.mk to not add CURDIR to DIRDEPS when it is SRCTOP.

# Much of the complexity here is for supporting cross-building.
# If a tree does not support that, simply using plain Makefile.depend
# should provide sufficient clue.
# Otherwise the recommendation is to use Makefile.depend.${MACHINE}
# as expected below.
# Note: this file gets multiply included.
# This is what we do with DIRDEPS
# DIRDEPS:
# This is a list of directories - relative to SRCTOP, it is
# normally only of interest to .MAKE.LEVEL 0.
# In some cases the entry may be qualified with a .<machine>
# or .<target_spec> suffix (see TARGET_SPEC_VARS below),
# for example to force building something for the pseudo
# machines "host" or "common" regardless of current ${MACHINE}.
#
# All unqualified entries end up being qualified with .${TARGET_SPEC}
# and partially qualified (if TARGET_SPEC_VARS has multiple
# entries) are also expanded to a full .<target_spec>.
# The _DIRDEP_USE target uses the suffix to set TARGET_SPEC
# correctly when visiting each entry.
#
# The fully qualified directory entries are used to construct a
# dependency graph that will drive the build later.
#
# Also, for each fully qualified directory target, we will search
# using ${.MAKE.DEPENDFILE_PREFERENCE} to find additional
# dependencies. We use Makefile.depend (default value for
# .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to
# distinguish them from others.
#
# Before each Makefile.depend file is read, we set
# DEP_RELDIR to be the RELDIR (path relative to SRCTOP) for
# its directory, and DEP_MACHINE etc according to the .<target_spec>
# represented by the suffix of the corresponding target.
#
# Since each Makefile.depend file includes dirdeps.mk, this
# processing is recursive and results in .MAKE.LEVEL 0 learning the
# dependencies of the tree wrt the initial directory (_DEP_RELDIR).
#
# NOTE: given the extent of processing that DIRDEPS undergoes it
# is important that any variables in entries use :U to guard
# against surprises when undefined.
#
# TARGET_SPEC_VARS
# The default value is just MACHINE, and for most environments
# this is sufficient. The _DIRDEP_USE target actually sets
# both MACHINE and TARGET_SPEC to the suffix of the current
# target so that in the general case TARGET_SPEC can be ignored.
#
# If more than MACHINE is needed then sys.mk needs to decompose
# TARGET_SPEC and set the relevant variables accordingly.
# It is important that MACHINE be included in and actually be
# the first member of TARGET_SPEC_VARS. This allows other
# variables to be considered optional, and some of the treatment
# below relies on MACHINE being the first entry.
# Note: TARGET_SPEC cannot contain any '.'s so the target
# triple used by compiler folk won't work (directly anyway).
#
# For example:
#
# # Always list MACHINE first,
# # other variables might be optional.
# TARGET_SPEC_VARS = MACHINE TARGET_OS
# .if ${TARGET_SPEC:Uno:M*,*} != ""
# _tspec := ${TARGET_SPEC:S/,/ /g}

# # We need to stop that TARGET_SPEC affecting any submakes
# # and deal with MACHINE=${TARGET_SPEC} in the environment.

# ONLY_TARGET_SPEC_LIST
# Defines a list of TARGET_SPECs for which the current
# directory can be built.
# If ALL_MACHINES is defined, we build for all the
# TARGET_SPECs listed.
#
# ONLY_MACHINE_LIST
# As for ONLY_TARGET_SPEC_LIST but only specifies
# MACHINEs.
#
# NOT_TARGET_SPEC_LIST
# A list of TARGET_SPECs for which the current
# directory should not be built.
#
# NOT_MACHINE_LIST
# A list of MACHINEs the current directory should not be
# built for.
#
# DIRDEPS_EXPORT_VARS (DEP_EXPORT_VARS)
# It is discouraged, but sometimes necessary for a
# Makefile.depend file to influence the environment.
# Doing this is correctly (especially if using DIRDEPS_CACHE) is
# tricky so a Makefile.depend file can set DIRDEPS_EXPORT_VARS
# and dirdeps.mk will do the deed:
#
# MK_UEFI = yes
# DIRDEPS_EXPORT_VARS = MK_UEFI
#
# _build_xtra_dirs
# local.dirdeps.mk can add targets to this variable.
# They will be hooked into the build, but independent of
# any other DIRDEP.
#
# This allows for adding TESTS to the build, such that the build
# if any test fails, but without the risk of introducing
# circular dependencies.
