config: Pass the compiler -Werror during warning detection
Otherwise the compilation prints a warning but exits with 0 return code.
However, later during the compilation, when -Werror is enforced to about
every file, the unsupported options start breaking the builds.
Tested: Ran configure with clang-3.5 and built libelf/ tree with it.
$ autoreconf -i
$ ./configure CC=clang-3.5 ...
$ make -C libelf
