description:
Make the TARGET_ENDIANNESS check only valid when making release, snapshot,
or distribution.

Also, clean up the check and include <sys/endian.h> instead -- some platforms'
<machine/endian_machdep.h> pull in the definitions of _BIG_ENDIAN and
_LITTLE_ENDIAN, invalidating the test; this makes the check values uniformly
"4321" and "1234" respectively.
