kmod: do not symlink config.guess/config.sub during autoreconf
I was encountering the following race condition on poky: - automake-native does do_install. - automake-native does do_populate_sysroot. This hardlinks config.guess and config.sub into ${D}. - kmod-native does do_configure. This runs `autoreconf`, which runs `automake --add-missing` (symlinks config.guess/config.sub from recipe-sysroot-native to build dir), then runs `gnu-configize` (copies _its own_ config.guess/config.sub _on top_ of the already existing ones). Since the destinations already had symlinks, the copy would overwrite config.guess/config.sub in recipe-sysroot-native, which would in turn overwrite the same in ${D} due to being hardlinked. - automake-native does do_package. The outhash is thus calculated on the clobbered config.guess/config.sub files. With hash equivalency enabled, the different outhash produced a different unihash, which kept me from reusing sstate between my laptop and my build server. This race condition would happen only on the build server (BB_NUMBER_THREADS = 32) but never on my laptop (BB_NUMBER_THREADS = 6). I didn't see the --install and --symlink flags being used by any other recipe, so I removed them, and that fixed the issue.
