Joel Sherrill 6c77bbab39 New autoconf feature from Ralf Corsepius:
It adds make rules for reconfiguring build-trees ("make Makefile") and
  adds dependency rules for configure and friends (i.e. calls autoconf).
  Most of this code has been "borrowed" from automake and was adapted to
  rtems.

  Addionally, I added automatic generation of the "aclocal.m4"-file by
  "aclocal" (from the automake package). Therefore I splitted aclocal.m4
  into several separate files (attached to this mail), each containing one
  of rtems customized autoconf/m4-macros and have put them into a new
  subdirectory "aclocal". Normal users won't be influenced and won't even
  need this, unless they try to modify configure.in.

  The main advantage of this is: these aclocal/m4-macros become reusable
  and easier to administer. As a disadvantage, rtems becomes dependent of
  having aclocal/automake installed. To keep building rtems functional if
  autoconf or aclocal isn't installed, the related Makefile commands are
  prefixed by "-" -- only an error message should be issued by "make".
