From: Lou Woods <lou.wo...@oarcorp.com>
rcmdsh() and innetgr() are referenced by rcmd, but aren’t available
in libbsd and are unresolvable external symbols when libbsd.a is
processed by the RTL.
innetgr() is part of netgroup and could be ported in at some point
in the future.
rcmdsh() uses fork() and exec() so uses of rcmdsh function have been
removed.
