It is documented in build(7):
buildworld Build everything but the kernel, configure files in
etc, and release. The actual build location prefix
used is ${MAKEOBJDIRPREFIX}${.CURDIR} for native
builds, and ${MAKEOBJDIRPREFIX}/${TARGET}${.CURDIR}
for cross builds and native builds with variable
CROSS_BUILD_TESTING set.
It might have been used in older releases for something more meaningful, but again… not sure why/how tinderbox does the right thing by MAKEOBJDIRPREFIX.
Cheers,
