I just changed the check in configure.ac from elf_begin() to
elf_getshdrstrndx().  Please give the SVN version a try.  If there's a
too old version of libelf only present, it should now correctly omit
it from the build.

Each extra switch is extra work, requires testing etc.  As most people
want all of the features they could possibly get, I rather tend to
auto-detect everything that is around.

You could always tweak ac_cfg.h after configure ran, if you really
want to disable a feature that has been positively probed by
configure.
