I think a UNIXMODE switch would be sufficiant.  The default should be not
to use /bin/sh (under both MiNT and TOS, for backward compatibelity of new
binaries to not-well-configured systems).  If UNIXMODE switch "s" is present,
/bin/sh should be used.  The device to load it from should be the default
root device (_rootdir), which is initialized from UNIXMODE, too (in
mntlib/main.c), and which defaults to U: under MiNT.
