* machine/types.h: Removed as a simpler version of this file is now part of the RTEMS newlib support. * machine/Makefile.am, machine/endian.h, nfs/bootp_subr.c, rtems/rtems_bsdnet_internal.h, sys/Makefile.am, sys/systm.h: Minor modifications to use the simpler machine/types.h. Mostly more complete sets of #include's to account for machine/types.h no longer doing this.
