Add support for the newworld apple macintosh (PPC). This has been tested on the powerbook 2000 only. It only adds support for generic ieee1275 functions, console and disk support. This should be easy to port to other architectures with support for Open Firmware. * configure.ac: Accept the powerpc as host_cpu. In the case of the powerpc cpu set the host_vendor to ieee1275. Make sure the i386 specific tests are only executed while building for the i386. Inverse test for crosscompile. * genmk.rb (Utility): Allow assembler files. * normal/cmdline.c (pupa_tab_complete): Reset pupa_errno. * conf/powerpc-ieee1275.rmk: New file. * disk/powerpc/ieee1275/ofdisk.c: Likewise. * disk/powerpc/ieee1275/partition.c: Likewise. * include/pupa/powerpc/ieee1275/biosdisk.h: Likewise. * include/pupa/powerpc/ieee1275/console.h: Likewise. * include/pupa/powerpc/ieee1275/partition.h: Likewise. * include/pupa/powerpc/ieee1275/time.h: Likewise. * include/pupa/powerpc/ieee1275/util/biosdisk.h: Likewise. * include/pupa/powerpc/ieee1275/multiboot.h: Likewise. * include/pupa/powerpc/ieee1275/loader.h * include/pupa/powerpc/setjmp.h: Likewise. * include/pupa/powerpc/types.h: Likewise. * kern/powerpc/ieee1275/init.c: Likewise. * kern/powerpc/ieee1275/openfw.c: Likewise. * term/powerpc/ieee1275/ofconsole.c: Likewise. These files were written by Johan Rydberg (jrydberg@night.trouble.net) and I only modified them slightly. * boot/powerpc/ieee1275/cmain.c: New file. * boot/powerpc/ieee1275/crt0.S: Likewise. * boot/powerpc/ieee1275/ieee1275.c: Likewise. * include/pupa/powerpc/ieee1275/ieee1275.h: Likewise.
