head -r333946(?) broke many builds

ci.freebsd.org shows -r333945 built okay (ignoring riscv64) but
later not ( -r333947 and later for most).

--- all_subdir_usr.bin/top ---
make[4]: make[4]: don't know how to make top.local.h. Stop

make[4]: stopped in /usr/src/usr.bin/top
*** [all_subdir_usr.bin/top] Error code 2

Interestingly FreeBSD-head-aarch64-build is not broken
at -r333947 but is later at -r333949 --for the same
error:
