Update the bootstrap script to be compatible with newer versions of GIT that changed the git clone -h output from containing: "--depth" to: "--[no-]depth" This bootstrap script is pulled the latest GNULIB version from GNULIB GIT, commit 9a1a6385 This change avoids a full clone on GNULIB, saving something like 50 MB.
