Below gives supporting context from an example failure.

In attempting to update my cross build (amd64 -> armv6 [or powerpc64]) from
-r302331 to -r302412 it failed with [armv6 example]:

--- init_keytry.h ---
sh: ./make_keys: Exec format error

This was based on:

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. [Does
not apply to the powerpc64 example.]
