configmake: support new --runstatedir option http://lwn.net/Articles/436012/ documents that many distros are now preferring to use /run rather than /var/run for storage of pid files and other per-process temporary files that must not be cleaned out during arbitrary TMPDIR sweeps. As such, the GNU Coding Standards were recently changed to recommend a new configure option to make it easy to choose this directory at configure time, and autoconf 2.70 will support the new directory by default. This patch adds support for propagating results of the new option (for new enough autotools) or providing a sane default (for older autotools) into C code. * m4/configmake.m4 (gl_CONFIGMAKE_PREP): Substitute runstatedir even if autoconf was too old to provide the command line option. * modules/configmake (Makefile.am): Propagate it to .h file.
