My modest single-core, single-procesor i386 w/2GB+2GBswap also works fine
with MAKE_JOBS != echo $$(($$(sysctl -n hw.ncpu) + 1)) building these
packages.

For the machine in question:

NetBSD 7.99.4 (GENERIC) #7: Mon Jan 26 18:49:37 CST 2015
        sysop%verthandi.technoskunk.fur@localhost:/d0/build/current/obj/macppc/sys/arch/ma
cppc/compile/GENERIC
total memory = 2048 MB
oea_startup: failed to allocate DEAD ZONE: error=12
avail memory = 1977 MB
[...]

$ swapctl -l
Device      512-blocks     Used    Avail Capacity  Priority
/dev/dk2       4195296        0  4195296     0%    0
/d0/swap       8388608        0  8388608     0%    1
Total         12583904        0 12583904     0%

Would there be messages logged to syslog if swap were exhausted?  If so,
the only occurances of [Ss][Ww][Aa][Pp] in /var/log/messages during the
time these packages were built are the copies of the kernel messages
where the disk partitions are detected during boot.
