The complete error message in the configure file is this:

"Installed libgccjit has failed passing the smoke test.
You can verify it yourself compiling:
<https://gcc.gnu.org/onlinedocs/jit/intro/tutorial01.html>.
Please report the issue to your distribution if libgccjit was installed through
that.
Here instructions on how to compile and install libgccjit from source:
<https://gcc.gnu.org/wiki/JIT>."

(I haven't yet tried building --with-native-compilation so I don't know
if the configure output shows the complete message.)
