Return to the build directory used to build the original GCC compiler (see Section 3.2.2). Delete the contents and reconfigure GCC this time to include a local prefix for searching (using the --with-local-prefix option to configure).

cd builddir-gcc
rm -rf *
../gcc-3.4.4/configure --target=or32-uclinux --prefix=/opt/or32 \
    --enable-languages=c --with-local-prefix=/opt/or32/or32-uclinux
	

The compiler will preferentially consider include and library files within the /opt/or32/or32-linux directory (in other words the target specific sub-directory of the installation directory), which can be used for all the Linux and uClibc files.
