Up to about a week ago building world on FreeBSD 10.2-STABLE went
just fine. Today after svn update the build fails:
# make buildworld
[...]
CC='cc ' mkdep -f .depend.getprotoent_test -a
-I/usr/src/lib/libc/tests/net -I/usr/src/lib/libnetbsd
-I/usr/src/contrib/netbsd-tests -std=gnu99
/usr/src/contrib/netbsd-tests/lib/libc/net/t_getprotoent.c
echo getprotoent_test: /usr/obj/usr/src/tmp/usr/lib/libc.a
/usr/obj/usr/src/tmp/usr/lib/private/libatf-c.a >>
.depend.getprotoent_test

Stop.

*** Error code 1
It turns out that our file system /usr/src had an "exec" flag
turned off, so now running a command:
/usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr
fails with "Permission denied".
It would be valuable if building a system on an exec-protected
src file system would continue to be possible.
Not sure if the
/usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr
is the only such new command breaking the build. Anyway, a simple
workaround is to run shell from a command line instead of as a
shebang, i.e.:
# /bin/sh /usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr
instead of:
# /usr/src/contrib/netbsd-tests/lib/libc/net/gen_ether_subr
