Add configure option --enable-build-timestamp.
* configure.ac (BUILD_TIMESTAMP): Set to "<none>" by default. -- This is based on libgpg-error commit d620005fd1a655d591fccb44639e22ea445e4554 but changed to be disabled by default. Check there for some background. Signed-off-by: Werner Koch <[email protected]>
