Description of problem:
The update to protobuf-2.5.0 broke building on ppc and ppc64:
libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I.. -Wall -Wwrite-strings -Woverloaded-virtual -Wno-sign-compare -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -c google/protobuf/io/zero_copy_stream_impl_lite.cc  -fPIC -DPIC -o .libs/zero_copy_stream_impl_lite.o
In file included from ./google/protobuf/stubs/atomicops.h:59:0,
                 from ./google/protobuf/stubs/once.h:81,
                 from google/protobuf/stubs/once.cc:38:
./google/protobuf/stubs/platform_macros.h:61:2: error: #error Host architecture was not detected as supported by protobuf
 #error Host architecture was not detected as supported by protobuf

protobuf-2.4.1 built and worked just fine on PowerPC, so please add the missing definition back into protobuf.
