c38367c73f was meant to eliminate runtime
function pointer modifications in autotools checks because they were
prone to false negatives on kernels hardened by the PaX project.
Unfortunately, I missed the xattr_handler and super_block->s_bdi
autotools checks. Recent changes to PaX constified
xattr_handler->get/set, which lead me to discover this oversight.
