You may want to give more details, such as the content of . . .

/etc/make.conf
/etc/src.conf
*.meta files for the failed commands (if any)

Listing some example *.meta file information from a cross build
(not likely problem files):

# cd /usr/obj/armv7_clang/arm.armv7/usr/src/arm.armv7/bin/sh
# ls -lTdrt *.meta
. . .
-rw-r--r--  1 root  wheel  4236 Dec 11 23:42:04 2018 nodes.o.meta
-rw-r--r--  1 root  wheel  3603 Dec 11 23:42:05 2018 sh.full.meta
-rw-r--r--  1 root  wheel   726 Dec 11 23:42:05 2018 sh.debug.meta
-rw-r--r--  1 root  wheel   739 Dec 11 23:42:05 2018 sh.meta

The files have details of commands used, error messages, files used,
and such. For example (no errors):

# more nodes.o.meta
# Meta data file /usr/obj/armv7_clang/arm.armv7/usr/src/arm.armv7/bin/sh/nodes.o.meta
