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