:range replaces var value with an integer sequence one per word
in the current var value.
:_ stores the current var value in $_ so that it can be referred to
later in the modifier series.

every platform. Thus setting OBJMACHINE, allowed one to keep
in-tree objdirs with multiple builds. With the advent of evb*, this
has become impossible until now. Introduce OBJMACHINE_ARCH that
adds ${MACHINE_ARCH} to the objdir so that we have unique objdirs
per build again. Until we restructure things to that this is not
necessary, it is the simplest fix.
well as *interrupted* targets to be deleted. The name and behavior of
the variable matches gmake.
Also fix a glitch in newline output on error in compat mode that I
discovered while doing it.
Closes PR 51376.
The filter is applied to paths Read or Excuted, and if it expands to
nothing, the entry is skipped.
For example; dirdeps.mk can set this to:
.MAKE.META.IGNORE_FILTER = M*/${.MAKE.DEPENDFILE_PREFIX}*
when checking if DIRDEPS_CACHE is up to date, where only Makefile.depend*
are of interest.
realpath(3) is expensive, and meta mode at least uses it extensively.
We use cached_realpath() to save the result of successful calls to
realpath(3) in a private variable context.
This improves the worst case performance (eg examining libc with
nothing to do) by a factor of 4.

Both meta_create() and meta_oodate() now share meta_needed()
to indicate if a .meta file is needed.
This allows for deciding that missing .meta file is cause of out-of-date.
The new knob 'missing-meta' controlls this, and is off by default
since the side effect files of generators like yacc will typically need
.NOMETA to avoid problems.
This however makes it much easier for folk to switch back and forth
with meta mode (eg. FreeBSD's normal build can leverage meta mode for
improved reliablility without need to clean).
Also if .MAKE.MODE does not contain 'nofilemon', the knob
'missing-filemon' allows control as to whether missing filemon data
should cause the target to be out-of-date.
Again off by default.
If -B compatMake will be true and should be honored.
If -j forceJobs will be true and the command line supplied .MAKE.JOBS
should be respected - for consistency with other usage.
