bootstrap: exit immediately upon gnulib-tool failure * build-aux/bootstrap: Exit immediately if gnulib-tool fails. This was noticed when gnulib-tool exited early due to failure to apply a patch in coreutils at http://hydra.nixos.org/eval/1172233, but various confusing errors were then given as the build proceeded.
