	* ChangeLog: Updated to reflect following patch.

Selective Cherry Pick of Roland McGrath's head commit
7967983f.  The configure.in and Makefile
parts are the same as Roland's patch but since this is a backport to a GLIBC
2.8 branch the individual configure files are different so those were
regenerated locally by Ryan.

Roland's ChangeLog is still relevant:

2009-09-15  Roland McGrath  <roland@redhat.com>

	* aclocal.m4 (GLIBC_PROVIDES): Add _AS_ECHO_PREPARE.
	* nptl/sysdeps/pthread/configure: Regenerated.
	* nptl/sysdeps/x86_64/configure: Regenerated.
	* sysdeps/unix/sysv/linux/configure: Regenerated.
	* sysdeps/x86_64/elf/configure: Regenerated.

	* Makefile (autoconf-it): Set execute bit only on top-level configure.

	* configure.in: Let add-ons set $libc_add_on_config_subdirs to have
	the effect of AC_CONFIG_SUBDIRS relative to the add-on directory.
	* aclocal.m4 (GLIBC_PROVIDES): Add AC_CONFIG_SUBDIRS.
	* configure: Regenerated.

This fix makes configure recurse into an add-on's standalone directories where
the directories in libc_add_on_config_subdirs (relative path to the add-on)
have their own pre-configured 'configure' and 'Makefile.in' that is maintained
'out-of-project'.
