freebsd stable - Jul 2016 - 11.0: amd64 -> armv6 -r302331 -> -r302412 re-cross-build (update): got "sh: ./make_keys: Exec format error" again for init_ketry.h in ncursesw

[Sending to freebsd-stable as well this time, adding the 11.0 reference to the
subject too.]
[Before the below cross build/update attempt I updated my amd64 from -r302331
-> -r302412.]

Summary: It appears that WITHOUT_META_MODE= still needs to be forced for cross
compiles at least sometimes in order to avoid "Exec format error". man
src.conf only mentions WITHOUT_META_MODE= in one place:
>     WITH_DIRDEPS_BUILD
. . .
>             WITH_META_MODE (unless WITHOUT_META_MODE is set explicitly)
. . .
>             This must be set in the environment, make command line, or
>             /etc/src-env.conf, not /etc/src.conf.

In attempting to update my cross build (amd64 -> armv6) from -r302331 to
-r302412 it failed with:

make.conf was empty.

The earlier -r302331 cross build had WITH_LIBSOFT= in use. -r302412 is my first
testing of WITHOUT_LIBSOFT= after rebuilding all ports to avoid libsoft.
