First off don't compile in the source tree.

Second can you show the exact command line that is being involved?

Invoking xgcc without any -B is not very useful. You either need to install GCC
before running or use a few -B options to get the correct directories.

This is not normal way of running GCC either.

When compiling gcc from source code, which parameter should give to configure
script? such as ${BINUTILS_SOURCE_DIR}/configure --prefix=${NATIVE_PREFIX}
--with-sysroot=${CROSS_PREFIX}  etc.

I don't understand your question and questions like these are better answered
on the gcc-help mailing list rather than here.
