Do not build libctf for targets that do not use the ELF file format.
top * configure.ac (noconfigdirs): Add libctf if the target does not use
the ELF file format.
* configure: Regenerate.
binutils* configure.ac (LIBCTF): Export. Set to empty for non-ELF based
targets.
(HAVE_LIBCTF): Define if libctf support is available.
* Makefile.am (LIBCTF): Set value to @LIBCTF@.
* objdump.c: Make CTF code conditional upon HAVE_LIBCTF being
defined.
* readelf.c: Likewise.
* configure: Regenerate.
* Makefile.in: Regenerate.
* config.in: Regenerate.
