Update miscellaneous files from upstream sources.
This patch updates miscellaneous files from their upstream sources:
texinfo.tex from Texinfo, config.guess and config.sub from config.git,
install-sh from automake and move-if-change from gnulib.

Tested x86_64 that installed shared libraries are unchanged by the
patch; also looked at the generated libc.pdf manual.

	* manual/texinfo.tex: Update to version 2014-05-05.10 with
	trailing whitespace removed.
	* scripts/config.guess: Update to version 2014-03-23.
	* scripts/config.sub: Update to version 2014-05-01
	* scripts/install-sh: Update to version 2013-12-25.23.
	* scripts/move-if-change: Update from gnulib.
