There must be another trick missing here...
Every time the ``make build'' attempts to create a new image, I get an
error message like
/usr/bin/ld: warning: cannot find entry symbol _start;
defaulting to <some-hex-number>
And, attempting to execute any dynamically-linked ELF image yields for
example:
/usr/src/usr.bin/banner/obj/banner: Exec format error. Binary
file not executable.
But I can successfully execute statically-linked ELF images, like
sbin/ping, without problem, even though they (the static images) also
got the above warning from /usr/bin/ld
