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.
