Makefile.am: Add frv support.

2004-08-30  Anthony Green  <green@redhat.com>

        * Makefile.am: Add frv support.
        * Makefile.in, testsuite/Makefile.in: Rebuilt.
        * configure.ac: Read configure.host.
        * configure, aclocal.m4: Rebuilt.
        * configure.host: New file.  frv-elf needs libgloss.
        * include/ffi.h.in: Force ffi_closure to have a nice big (8)
        alignment.  This is needed to frv and should harm the others.
        * include/ffi_common.h (ALIGN_DOWN): New macro.
        * src/frv/ffi.c, src/frv/ffitarget.h, src/frv/eabi.S: New files.
