[hackers] [sbase] [PATCH] *sum: Ignore -b and -t flags

From: Michael Forney <mforney_AT_mforney.org>
Date: Wed, 1 Jan 2020 22:04:47 -0800

These tools are not standardized, but these flags are supported in all
implementations I'm aware of (coreutils, busybox), and are occasionally
used in scripts.

These flags are only meaningful on operating systems which differentiate
between text and binary files, so just ignore them.
