cc/gcc: Remove copyheaders toggle in do_cc_core_backend, make default

Browse Source 
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

Having all modes of the core compiler copyheaders from CT_HEADERS_DIR
(in combination with previous patch for newlib to add a do_libc_start_files
function to copy into the CT_HEADERS_DIR) resolves this.
