See <https://sourceware.org/ml/libc-alpha/2014-01/msg00575.html> and the 
discussions in bug 22825.  I think that by incrementally changing the 
information contained in the ldconfig cache, it might well be possible to 
eliminate much of the need for architecture-specific readelflib.c files.

We don't have such a configure option for support in localedef for 
building locales for other glibc systems; it's not obvious we should have 
one for ldconfig either.
