Hi Eli,

if the interface we'd like to expose is the through file-local variables
then this should work already for `comp-speed' and `comp-debug',
I'extend it for `comp-native-driver-options'.

Setting comp-speed to -1 achieve something close but still producing a
.eln as output.  I guess we want also a way to prevent
native-compilation entirely correct?

Thanks
