[PATCH] xfsprogs: more autoconf modernisation

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

Fix a few autoconf things that were added after the submission of the
autoconf modernization patch.  This was performed by running:

$ autoupdate configure.ac m4/*.m4

And manually putting the version back to 2.69.
