# This is necessary, because the resulting library has
# /tmp/nix-build-jbig2enc/src/.libs before /nix/store/jbig2enc/lib
# in its rpath, which means that patchelf --shrink-rpath removes
# the /nix/store one. By cleaning up before fixup, we ensure that
# the /tmp/nix-build-jbig2enc/src/.libs directory is gone.
