Failing buildword due to execution permission (with fix)

Hello,
I have this buildwordl failure:

===> libexec/rbootd (depend)
--- depend_subdir_lib ---
--- aton_ether_subr.c ---
/usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr 
/usr/src/sys/net/if_ethersubr.c ato
n_ether_subr.c
sh: /usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr: 
Permission denied
*** [aton_ether_subr.c] Error code 126


I fixed with:
chmod +x /usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr


This was from a fresh checkout of current on a new machine.

Is it me or shall I report a bug?

Regards,
