Since make release is toast anyway, add wood to the pyre:
This significantly rewamps libdisks discovery of existing disk layout. Please send me reports if this does not work as expected on i386 or sparc64 platforms. I need to sort out alpha, pc98 and ia64 (in that order) before testing on those platforms make a lot of sense. Belived to work for: i386 sparc64 Unknown state: pc98 alpha ia64
