Add the config option --enable-new-config to use later versions of

config.guess and config.sub for the packages that use autotools.

With this option, we can (mostly) build libelf, libdwarf, libmonitor,
libunwind, libxml2, open-analysis and xerces on powerpc/le and ARM
(not all points in the matrix work).

This is mostly a temporary option.  At some point, we will use the new
config.guess always.
