Gcc configuration error

I am trying to build GNU toolchain for OpenRISC by following the guide given at http://openrisc.net/toolchain-build.html#_stage_1_gcc on Fedora Virtual Box Image. I am getting error saying Configure: error: cannot run /bin/sh ../gcc-svn/config.sub when I try to configure gcc using the command. ../gcc-svn/configure --target=or32-linux --prefix=$PREFIX \ --disable-libssp --srcdir=../gcc-svn --enable-languages=c \ --without-headers --enable-threads=single --disable-libgomp \ --disable-libmudflap The full content of config.log is as below This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by configure, which was generated by GNU Autoconf 2.64. Invocation command line was $ ../gcc-svn/configure --target=or32-linux --prefix= --disable-libssp --srcdir=../gcc-svn --enable-languages=c --without-headers --enable-threads=single --disable-libgomp --disable-libmudflap ##
