Automake 1.12 released, with warnings of future incompatibilities

I especially note the "WARNING: Future backward-incompatibilities!"
section - of the items listed, AM_CONFIG_HEADER is the only one I
remember seeing in the X.Org configure.ac's, and we've converted a
lot of them to AC_CONFIG_HEADERS, but at least in the modules I've
checked out, I see some remaining to fix still (though some of these
are dead, like xtrap & libxkbui, others like pixman & xts certainly
are not):

pixman/configure.ac:AM_CONFIG_HEADER(config.h)
app/xrx/configure.ac:AM_CONFIG_HEADER(config.h)
app/xtrap/configure.ac:AM_CONFIG_HEADER(config.h)
driver/xf86-input-vmmouse/configure.ac:AM_CONFIG_HEADER([config.h])
driver/xf86-video-impact/configure.ac:AM_CONFIG_HEADER([config.h])
driver/xf86-video-openchrome/configure.ac:AM_CONFIG_HEADER([config.h])
driver/xf86-video-sunbw2/configure.ac:AM_CONFIG_HEADER([config.h])
lib/liblbxutil/configure.ac:AM_CONFIG_HEADER(config.h)
lib/libxcwm/configure.ac:AM_CONFIG_HEADER(config.h)
lib/libXevie/configure.ac:AM_CONFIG_HEADER(config.h)
lib/libXfontcache/configure.ac:AM_CONFIG_HEADER(config.h)
lib/libxkbui/configure.ac:AM_CONFIG_HEADER(config.h)
lib/libXTrap/configure.ac:AM_CONFIG_HEADER(config.h)
test/xts/configure.ac:AM_CONFIG_HEADER([config.h])
util/imake/configure.ac:AM_CONFIG_HEADER(config.h)
util/makedepend/configure.ac:AM_CONFIG_HEADER([makedepend-config.h])
xcb/demo/configure.ac:AM_CONFIG_HEADER(config.h)

The only references I see to $(mkdir_p) in our Makefile.am are comments
warning against its use.
