[svn-r26326] Merge of r26275 from the trunk
- Updated configure.ac so that the direct VFD can now be built
without specifying _GNU_SOURCE, etc. on the command line.
- The direct VFD is now disabled by default. It was previously
enabled, but the configuration script couldn't configure it
properly, making it a moot point.
Fixes: HDFFV-9057, HDFFV-7567, HDFFV-9088, HDFFV-7566
Tested on jam (configure/make in various configurations only)
