# tar.xz archive, autoconf has an implicit dependency on HOST_XZ. By
# enabling XZ_AUTORECONF we also make host-xz depend on autoconf,
# which we can't do. It is also not necessary as we're autoreconfuring
# the target package to fix static build with musl, which is
# irrelevant for the host package.
