All symbols prefixed with PUPA_ and pupa_ are renamed to GRUB_
	and grub_, respectively. Because the conversion is trivial and
	mechanical, I omit the details here. Please refer to the CVS
	if you need more information.

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.

	* kern/rescue.c (pupa_rescue_cmd_rmmod): Call pupa_dl_unload, if
	possible.

	* kern/dl.c (pupa_dl_ref): Refer dependending modules
	recursively.
	(pupa_dl_unref): Unrefer depending modules recursively.
	Don't call pupa_dl_unload implicitly, because PUPA can crash if
	a module is unloaded before one depending on that module is
	unloaded.
	(pupa_dl_unload): Unload depending modules explicitly,
	if possible.
