This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.
The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.
This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile. Remove the now-unnecessary .keep_me files
whilst here.
Per lengthy discussion with Andrew Brown.
two ways:
- the child gets its pid as retval[0] (userland stub will turn it into a 0),
retval[1] is 1 and it is 0 in the parent.
- in the child, the fork syscall is successful, hence we must skip the next
instruction.

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

before rev 1.4. This change makes OF 2.4 machines actually boot, and
it works fine on my OF 2.01 machine. No reports of failures on other
archs.
I expect this change is fine as the original code flushed the just-loaded
ofwboot out of the cache, conditionalized on FIRMWORKSBUGS. In rev.
1.4, the code got in-lined, and changed to actually flush low memory
out of the cache. Since machines kept booting, I expect the firmware
was really flushing the binary out of the cache, so we're fine.
rely on default value. It should actually be extracted
from the bootpath instead, but that involves translating
from apple partition map entries to netbsd disklabel entries.
are related to using libsa's alloc(). Problems go away with this alloc().
The problem is that the libsa alloc() assumes we can grab memory off
the end of the program. That assumption doesn't work for us. It's
much better to use the alloc() we were using as it calls OF_claim()
to get memory.
