bsd.obj.mk: move MKHOSTOBJ to bsd.own.mk

Add default for MKHOSTOBJ=no to to bsd.own.mk _MKVARS.no.
Simplify bsd.obj.mk check.

get rid of old style `` command substitution in shell and use $() instead.

Prevent 'make obj' creating an objdir inside an objdir. This happens the

Back in 1993 ${MACHINE} was a unique way to define objdirs for
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.

Use ltarg=`stat -qf '%Y' $l` to read a symlink's target (and rely upon
a non-zero exit value to indicate a missing file or non-symlink),
instead of test -h $l && ltarg=`ls -ld $l | awk '{print $NF}'`
since the former is quicker and more concise.

whitespace cleanup

Add a BUILDID variable, which further qualifies object directories.

Remove spurious '.' in line 42, as reported by Naoto Shimazaki on
current-users on Thu, 29 Nov 2001 09:17:16.

Use :U successfully this time. In an expression such as ${FOO:D:Ubar}, you
end up with empty string if FOO is defined, and `bar' if it is undefined.

If using MAKEOBJDIRPREFIX use the same checks as the symlink logic does below.

i.e. if the root of the object tree doesn't exist then complain and exit.

This makes both sections consistant to each other (MAKEOBJDIR specifies an
exact directory so there's no root per se to check so nothing can really be
done there).

:U can't be used to test for existence, as the variable may contain an
arbitrary value; change back to .if !defined(). Problem noted by
bernd@arresum.inka.de in PR toolchain/14629.

Turn off host-specific objdirs by default. Set MKHOSTOBJ=yes to enable.

Also handle the USR_OBJMACHINE case for OBJHOSTMACHINE.

Affix the ${HOST_OSTYPE} info to the end of the objdir name if OBJMACHINE
is set (and MAKEOBJDIR[PREFIX] is not in use). This permits multiple hosts
to compile hostprogs (not just src/tools) for a given target without
colliding with each other.

Currently restricted only to new toolchain builds, as this requires a new
make(1) in order to function properly.

Fix variable concatenation in previous.

Make the BSDSRCDIR/BSDOBJDIR symlink based objdir system work for the top
source directory. This will use BSDOBJDIR of OBJMACHINE is unset, and will
create a directory '.MACHINE' inside BSDOBJDIR if OBJMACHINE is set.

MAKEOBJDIR and MAKEOBJDIRPREFIX based objdirs already cope with the top
level directory just fine.

Use __curdir throughout, so MAKEOBJDIR builds see resolved paths in the
"foo -> bar" messages written to stdout.

Protect against multiple inclusion, and evaluate ${.CURDIR} early (to assist
the top-level toolchain bootstrap).
