That line is not a typo. Without it, both builtin.lib-generator and 
intel-linux.prebuilt would be tried, and both succeed, that that would be an 
ambiguity.

In fact, there should be extra line:

  generators.override intel-linux.prebuilt : builtin.prebuilt ;

that resolves conflict between another pair of generators in favour of
intel-linux.prebuilt.

I've comitted the fix, thanks for reporting!
