Many people are being bitten by the fact that if they select
CONFIG_PARTITION_ADVANCED in order to get some additional support,
they suddenly lose support for the MSDOS_PARTITION type.

Moreover, everybody needs MSDOS_PARTITION - also people not on i386,
since it is the type used on smart media and compact flash and
similar cards.

So, the below advises people "Say Y here" for MSDOS_PARTITION,
and does not change the default choices when PARTITION_ADVANCED
is selected.
