Hi Anatole,

generally speaking we do not support cross compilation using the native
build as libgccjit AFAIK is just not made for cross compiling.  I
suspect in your specific case this should be possible with some hacking
but coming to the problem of bypassing the smoke test I think the
easiest is to start with is commenting it out from configure.ac.
