Configure script checks for libparted version >= 3.2 to automatically
determine the availability of online resize capability in libparted.
This can be overridden from the ./configure command line.  Override
enable when an older version of libparted has been patched to include
online resize support with:

    ./configure --enable-online-resize

Override disable with libparted 3.2 or later to disable the feature when
it is not wanted with:

    ./configure --disable-online-resize

Note that GParted also requires, and checks for at runtime, Linux
kernel >= 3.6 for online resize support.  See commit for more details:
