Disable building of {mkfs,fsck}.minix, which are used
to support minix file-systems. Minix predates Linux and
support for its file-systems is unlikely to be needed.
No recipes otherwise reference minix, except in patches
to autotools configuration scripts, so there should be no
impact to other recipes.
