I thought ISL 0.15 has some new features you could check? Also using a run test is bad for cross compiling. I'd simply change the "compatible" test to check for isl_ctx_get_max_operations or whatever is needed to implement the compute bound and not worry about warning about using a deprecated ISL during configure.
