Hi,
This patch is RTEMS specific and needed so we can build
all AVR and H8300 multilib variants of RTEMS.

* libc/sys/rtems/machine/sys/param.h: Conditionalize definition of
BLKDEV_IOSIZE and MAXPHYS so it will fit into small memory targets.
This is needed to build all AVR and H8300 RTEMS multilib variants.
