Changes to existing files to enable building AARCH64 userland.
evbarm64-el
This is clang only. While gcc4.8 supports aarch64, no netbsd support has
been written for aarch64 with gcc4.8.

branches: 1.18.2;
Add a dependency on etc.${MACHINE}/MAKEDEV.conf

Add a dependency for Makefile so that when you add device to the Makefile
it will automatically regenerate the device mtree file and cause the ramdisk
to be updated.

Tweak MAKEDEVSPEC target to properly report MAKEDEV failures:
- No need to ignore `rm -f' failures which should not happen.
- Do not pipe MAKEDEV output, but use a temp file.

branches: 1.15.18;
Use ${TOOL_SED} instead if plain sed in Makefiles.

Fix tyop.

branches: 1.13.12; 1.13.14;
MAKEDEV.subr no longer exists. Don't install it in any ramdisk
or miniroot images.

Invent MAKEDEVSUBR and add it to IMAGEDEPENDS and PARSELISTENV if
appropriate. Previously, IMAGEDEPENDS did not include MAKEDEV.subr.

Remove "./dev type=dir" entry from generated devices.spec, as it
causes the ownership of ${.OBJDIR}/work/dev to be used in the image
instead of that from the earlier entry in work.spec.

MAKEVERBOSE support

When using "MAKEDEV -s" to generate a specfile, rewrite the paths from
"./" -> "./dev/". Noted by Tetsuya Isaki <isaki@NetBSD.org> in private mail.

Rework MAKEDEV:

* Use "mknod -F netbsd -r" to create nodes, instead of
"rm ; mknod; chmod; chown".
This means permissions & ownership of existing nodes will
not be changed.
This is up to 30% faster when populating an empty /dev,
and nearly 2x faster when re-running on an existing /dev.

* New options:
-f force change of permission & ownership of existing
devices
-m mknod override name/path of mknod program
(which defaults to $TOOL_MKNOD, then "mknod").
-s generate mtree(8) specfile instead of creating devices

* Remove /usr/etc from $PATH; not needed anymore.

* Provide functions to create devices & directories:
mkdev name [b|c] major minor [mode{=600} [gid{=0} [uid{=0}]]]
create device node `name' with the appropriate permissions
lndev src target
create a symlink from src to target
makedir dir mode
create directory with appropriate mode

* UIDs and GIDs are hardcoded in at MAKEDEV generation time.
(Unfortunately there's not a simple way of determining a GID
a la "id -n user" for determining a UID).

This was tested by generating MAKEDEV for each MACHINE,MACHINE_ARCH
combination and comparing the results of "MAKEDEV all" from the
previous version to the new one.
(This testing actually highlighted mistakes in the previous configuration!)


Simplify distrib/common/Makefile.makedev to use "MAKEDEV -s"

Update for MAKEDEV.tmpl changes; use <.OBJDIR-of-etc>/MAKEDEV
instead of etc/etc.${MACHINE}/MAKEDEV

use ${HOST_SH}

add multiple-include protection.
clean up some comments.

a minor heads-up. (if i got bit by this, someone else might)

correct a comment

branches: 1.2.2;
replace _SRC_TOP_ with NETBSDSRCDIR, since the latter is the "public" version

- cleanup image device creation: add Makefile.makedev & list.makedev,
remove dist/*, now that they're not needed.
if MAKEDEVTARGETS is set, use MAKEDEV.wrapper and makedev2spec.awk to
create an mtree specfile containing the devices that would be made with
"etc/etc.${MACHINE}/MAKEDEV $MAKEDEVTARGETS".
otherwise, copy etc/etc.${MACHINE}/MAKEDEV to dev/MAKEDEV (via list.makedev)
- add mtree.common; contains directories used by all images, and optional
entries for dist/*
