commit: http://git.buildroot.net/buildroot/commit/?id=ebe6154ff4b2a7399f6d3b66dba01c71237cf133
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When switching the git helper over to a shell script, a special case was
not carried over: in case the remote has the required reference, we
attempt a shallow clone, using --depth 1. However, this is not supported
when the remote is accessed with the http protocol.

Therefore, the download fails.

What happened before the conversion to a shell script was that the helper
in the Makefile would fallback to doing a full-clone.

This is the case and behaviour that were lost in the conversion.

To avoid making the script too complex, we only attempt a full clone if
needed. And we decide that a full clone is needed by default; we decide
it is unnecessary if the remote has the needed reference *and* the
shallow clone was successful.
