This is very old...

Good idea. Better to start with the current version.

It seems you have not correctly setup the ELDK. Have you set the
CROSS_COMPILE variable ?
$ echo $CROSS_COMPILE
ppc_4xx-

Yes, rule was changed. You see the taishan in boards.cfg

Makefile does not require anymore to have the _config rules. Definitions
for each board are set in boards.cfg

The taishan is compiled clean without problems on my PC. Check how to
start with ELDK:

Anyway, this should be enough:
$ export CROSS_COMPILE=ppc_4xx-
$ make taishan_config
$ make

Path is ok, but you need to export at least the CROSS_COMPILE variable.
