Patch by Vance Lankhaar <vlankhaar@linux.ca> to automaticly regenerate the
build options, so we will always have the right values for how and when an smbd was built. In particular, this is indended to address bitrot caused by configure.in changes. Andrew Bartlett (This used to be commit 2be258071c71986ba9af01e9a09ec49909a620dd)
