This probably won't work without major effort.

You are misinterpreting --program-prefix.
--program-prefix is the "program-prefix" to be used to prefix programs
when installing them. In general, for example, configuring a package
with --program-prefix=foo- will cause a program "prog" to be installed
For RTEMS --program-prefix is meaningless.
What you actually are looking for is CC_FOR_TARGET
(cf. configure --help of rtems-4.6pre3).
In your case, you have a chance to getting started with something
similar to this:
configure --target=powerpc-rtems CC_FOR_TARGET=ppc-elf-gcc
Anyway, I would recommend using a powerpc-rtems-toolchain instead.
