It seems, setting WITH_AUTO_OBJ in /etc/src-env.conf causes an error.
At least, removing it fixes build for me.

Build successful with the following settings:
# cat /etc/src-env.conf
WITH_META_MODE=
#WITH_AUTO_OBJ=

# env | grep MAKE
MAKEOBJDIRPREFIX=/home/obj

# cat /etc/make.conf
MALLOC_PRODUCTION=yes
KERNCONF= GENERIC-NODEBUG
CPUTYPE?=native
PORTS_MODULES= graphics/drm-next-kmod 
DOC_LANG = en_US.ISO8859-1 ru_RU.KOI8-R 
WITH_DEBUG_PORTS = mail/neomutt
WITH_CCACHE_BUILD=yes
CCACHE_DIR=/home/ccache
DEVELOPER=yes
