newfs and mount the target filesystem.
In Hauke's words: "Basically, the mac68k md_make_bsd_partitions() function,
which replaces the MI make_bsd_partitions() because the mac68k port does not
have an on-disk BSD disklabel, neglected to sign up BSD partitions for
newfs'ing and mounting by setting the appropriate flags."
Revert the commit to the install notes (rev. 1.14 of notes/mac68k/prep) which
added a warning and a workaround for this bug, as requested by hubertf in the
PR log.
