Add compatibility with Newlib header files. Some FreeBSD header files
are mapped by the translation script:
o rtems/bsd/sys/_types.h
o rtems/bsd/sys/errno.h
o rtems/bsd/sys/lock.h
o rtems/bsd/sys/param.h
o rtems/bsd/sys/resource.h
o rtems/bsd/sys/time.h
o rtems/bsd/sys/timespec.h
o rtems/bsd/sys/types.h
o rtems/bsd/sys/unistd.h
It is now possible to include <sys/socket.h> directly for example.
Generate one Makefile which builds everything including tests.
