Patch rtems-rc-20000627-1 from Ralf Corsepius <corsepiu@faw.uni-ulm.de>

that is part of the multilib/gnu-canonicalization movement:

Changes:
  * New m4-macro: aclocal/multilib.am
  * Suppress multiprocessing if --enable-multilib is given to
    configure

Notes:
  For now this patch only suppresses multiprocessing if
  --enable-multilib is given to configure and should not have any
  other side-effects, ie. it works around a minor issue which prevents
  introduction of multilibs in general.

  The RTEMS_ENABLE_MULTILIB_MASTER macro is the core part to build
  real multilibs, but can not be applied before other multilib related
  issues with RTEMS have been solved. (e.g. sptables.h, bsp_specs,
  Cygnus/Gnu canonicalization, _RTEMS_version, targopts.h, changing
  the installation point/tooldir support, etc.).
