* 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.
* libc/include/machine/_types.h: New file.
* libc/include/sys/types.h: Do not check for __rtems__
when including <machine/_types.h>. Remove some redundant
declarations now that <machine/_types.h> is included.
* libc/sys/rtems/machine/_types.h: Removed. Replaced with
shared header file.
* libc/include/sys/types.h [__rtems__]: Include new
header file machine/_types.h.
* libc/include/machine/types.h: Ditto.
* libc/sys/rtems/machine/_types.h: New file.
* libc/sys/rtems/machine: New directory.
* libc/sys/rtems/machine/limits.h, libc/sys/rtems/machine/param.h,
libc/sys/rtems/sys/param.h, libc/sys/rtems/sys/syslimits.h,
libc/sys/rtems/sys/utime.h: New files added to make *-rtems newlib
targets more BSD like when installed without requiring files to
be overwritten at install point when RTEMS itself is installed.
* Makefile.am: Pick up system dependent machine .h files such as
might be found on a BSD-ish system.
* Makefile.in: Regenerate.
* libc/include/machine/types.h: When on an RTEMS target, define a
few BSD flavor types.
