Both machines have the same architecture, therefore it is not a cross
build, I believe.  For my direct builds (both build and consumer
machines are x86-64) I use the procedure described in the handbook
(``23.6. Tracking for Multiple Machines''[1]).

A quote from release(7) man page:

release.sh checks out the src/, ports/, and doc/ trees to CHROOTDIR...

Therefore, release(7) "ignores" /usr/ports and uses
${CHROOTDIR}/usr/ports.  My build machine doesn't have access to the
Internet, therefore, I have to define the PORTS_UPDATE_SKIP variable and
provide ports tree into the ${CHROOTDIR}/usr/ports before
I will call /usr/src/release/release.sh.

/usr/src/release/release.sh defines DISTDIR=/tmp/distfiles when it
installs the textproc/docproj port or a port from the ${EMBEDDEDPORTS}.

As for why fetch(1) fails with bad system call under chrooted
environment -- I don't know.  I failed on a port fetching only if I
hadn't provided all necessary distfiles.  You have checksum error
message which is causing refetching of the ports-mgmt/pkg port.
Therefore, I believe
${CHROOTDIR}/tmp/distfiles/freebsd-pkg-1.14.2_GH0.tar.gz exists on your
file system (remained from a previous fetch try?)...  May be you should
try fetch(1) from the chrooted environment manually, to get any content?
