Add a 'mini-memstick.img' release target, which will use the
'bootonly.iso' components to create a smaller memory stick image.

This is useful for system recovery, where a full memstick.img image
is not necessarily needed (or wanted).  In addition, it is possible to
do bootonly-style installation, where the base.txz, kernel.txz, etc.
are fetched from a remote source.

Provide backwards-compatible target (mini-memstick), to keep in sync
with the targets documented in release/Makefile.

Use `pkg -vv' to obtain ABI for validating a chosen media server (done
prior to diving head-long into a pkg-update(8), et. al). This should
also be more future-proof than what was being done just before this.

Extend loader_delay as-documented in beastie.4th(8) and delay.4th(8), making it available to architectures that do not use or load the beastie
menu. This is reported to save headaches on some PPC systems where unload
followed by load does not produce the desired results wherein if-given
the opportunicy to abort the initial loading sequence, you can customize
the first load.

Yet, another attempt to fix the libm breakage due to the
changes in s_roundl.c to use bit twiddling.

Fix a bug that prevented `-d' from working as-documented in sysrc(8).
Rather, prevent a bunch of debugging information from spewing onto the
screen when using the `describe' flag (misinterpreted as `debug' by
the automatatic initialization routines).
Instead of modeling the kernel-tools build after the bootstrap tools, build
kernel tools the way cross-tools get built.  This seems to result in the
tool getting installed in the right place.  It also seems more correct in
retrospect, because if a tool emitted code or binary data as part of
building the kernel, it should do so in target-specific ways (endianess,
architecture, whatever).  That issue is moot for aicasm, our only current
tool, but it still seems to be more correct in principle.
Add new `--version' long option for getting the version (good for
comparing against the ports revision).
Add a `-c' option for `check only' to determine if a value is set
(get command) or if the current value is the same as what is desired
(set command). In those cases, the return status is success.
Otherwise, if the variable is unset (get command) or set to a different
value that what is desired (set command), returns with error status.
This is useful for puppet integration as well as everyday scripting.
