HEAD fails to build with -g1

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.

1. ./boot && ./configure && make -j
2. Observe failure

The failure (trimmed):
