In:

https://ci.freebsd.org/job/FreeBSD-main-armv7-build/26181/consoleFull

I see:

. . .
export 'MAKEOBJDIRPREFIX=/workspace/obj'
rm -fr /workspace/obj
. . .
sudo make -j 12 -DWITHOUT_CLEAN buildworld 'TARGET=arm' 'TARGET_ARCH=armv7' '__MAKE_CONF=/workspace/freebsd-ci/jobs/FreeBSD-main-armv7-build/make.conf' 'SRCCONF=/dev/null'
. . .
sudo make -j 12 -DWITHOUT_CLEAN buildkernel 'TARGET=arm' 'TARGET_ARCH=armv7' '__MAKE_CONF=/workspace/freebsd-ci/jobs/FreeBSD-main-armv7-build/make.conf' 'SRCCONF=/dev/null'
. . .

In:

https://github.com/freebsd/freebsd-ci/blob/main/jobs/FreeBSD-main-armv7-build/make.conf

I see just:

QUOTE
KERNCONF=GENERIC GENERIC-MMCCAM
END QUOTE

I do not see anything explicit related to what SRC_ENV_CONF is for
binding to, so a default context for that binding.
