Which likely means you're trying to compile for ppc64, which isn't  
ready - the sources are not yet being compiled in, so there are  
undefined symbols. I will shortly apply part of a patch, so that it  
should error out in case someone unknowingly runs into it.

...because you would need to use --build=powerpc-redhat-linux instead,  
since you cannot cross-compile from ppc64 to ppc either.

Most likely you do not need to pass --build or --target at all, just  
assure that gcc compiles 32-bit by default or set appropriate options,  
e.g., CPPFLAGS="-m32" or CC="gcc -m32" if necessary. The pointer size  
in a test program is used to decide if the ppc64 or 32-bit ppc path is  
taken.
