You will need to modify the build system to work well with TARGET_ARCH=powerpc (and I think it would be more reasonable to use TARGET_ARCH=ppc, but still)
For example, you need at the minimum to write a file named build/core/combo/ linux-ppc.mk which will contain PowerPC-specific definitions to be used during the build. This includes defining a set of default include paths for all compilations. You will probably need to write an AndroidConfig.h file, which is forcibly included by all compilation commands and defines a host of macros specific to the target platform. I don't remember where these are located, but there are already examples for a variety of platforms somewhere, they should be easy to find. Look at build/core/combo/linux-arm.mk for a valid example.
