commit: http://git.buildroot.net/buildroot/commit/?id=225189803d9ecb07aef3f7f016376c7eb00dc44d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The sparse_super feature is more efficient in terms of speed and
available space, so set it by default if supported, i.e. for revision 1.

This gives a huge speed gain for large resize2fs operations, especially
for expansion.
