Hi Andreas,

Super thanks!

I've rebased your branched, did some minor changes (broke two long lines
and squashed two commits).

I pushed it in scratch/native-comp-gcc-driver-options as I was thinking:

Okay if the libgccjit feature is not available we raise an error, but
how the user is supposed to test for this feature without compiling?

'comp-libgccjit-version' starts working only if gcc_jit_version_major is
available otherwise return nil, and I added gcc_jit_version_major into
GCC10 :/

We need to offer a way to the user to check for that before going for
compilation.  The only idea I've at the moment is that we expose a
function to set these instead of using 'comp-native-driver-options'.

Any thoughts?

  Andrea
