I've committed your patch, after making a few changes (see below).

I've updated to 0.12.2 and used the .bz2 tarball. Updating to 0.13 was
not possible due to incompatibility with cloog.

I had to use ISL_LIBTOOL_PATCH = NO to disable applying our Buildroot
libtool patch, which wasn't applying properly. It was anyway
unnecessary since it's a host only package.
