PATCH, libiberty: sort AC_CHECK_FUNCs

[Ben Elliston]

In this message:
  http://gcc.gnu.org/ml/gcc-patches/2009-08/msg00589.html

DJ notes that the list of functions in the AC_CHECK_FUNC invocation used
to be in alphabetical order.  This patch fixes this--double checked with
sort(1).  Found a couple of duplicates like gettimeofday and memcpy, so
this patch improves build times. :-)

OK for the trunk?
