GCC is always relocatable, you can move the installation and it will work in a different location. > It fails saying /usr/include directory is not present in the <prefix-dir>. > Have I missed something again? Did you read the docs for --with-sysroot? It tells the build process to use the headers and libraries under the sysroot directory instead of the ones in /usr - so if you have no headers and libraries in the sysroot directory then it will fail to find them.
