[PATCH] bootstrap: fix an error when gnulib is not used as a git submodule.

[Giuseppe Scrivano]

another small patch for bootstrap.

The redirect is needed because "git COMMAND -h" sends output to stderr.

Cheers,
Giuseppe

* build-aux/bootstrap (gnulib_path): If its length is zero then
assign "gnulib" to it.
* build-aux/bootstrap: Redirect "git clone -h" stderr to stdout.
