 I wanted to see how `-g1` vs `-g2` impact compile speed. Unfortunately I
 get linking errors trying to build GHC with `-g`.

 Steps:
 1) Add {{{
 GhcLibHcOpts += -g1
 GhcRtsHcOpts += -g1
 }}}
 to `mk/build.mk`. I used devel2 flavor.
 2) `./boot && ./configure && make -j`
 3) Observe failure

 The failure (trimmed):
