Another hadrian option you might want to use

[Matthew Pickering]

Hi,

A recent change in the testsuite meant that we now running the haddock
tests with hadrian, this means that haddocks for ghc/base get rebuilt
if you modify anything in the compiler.

This can decrease interaction speed. To disable the documentation
tests from running use

--docs=none

This is similar to the flag which already skips performance tests:

--skip-perf

Cheers,

Matt
