scripts/gcc.sh: Add copyheaders section for baremetal canadian

Canadian Cross compile for baremetal fails with error;

  checking for the value of EOF... configure: error: computing EOF failed

which is due to libstdc++ configure not being able to find stdio.h

We can copy the required headers from the newlib source into the prefix
include directory - to ensure both the final compiler for build and final
compiler for host have access.
