Noticed while trying to build ghc 8.2.1, and ghc 8.2.2 on alpine linux
armhf as well as nixos. Opening this ticket as I previously thought this
was just some quirk of the alpine linux port but managed to find out from
dhess on irc that nixos hits the same issue for both as well on armv7l
arches.
What happens. 8.2.1 logs, 8.2.2 has similar or the same issues, I was just
double checking that 8.2.1 has the same problems.

I've been poking around but i'm a bit out of my depth here in
understanding the ghc rts here and debugging it as well. But its curious
that only the stage2 compiler is having issues being built and not stage0
or stage1.
If needed/desired I can provide access/login to this box for debugging but
its sloooow, ~29 hours to do a build to this point.
But I'm willing to help move things along, ghc on arm is one of the main
reaons for the port to alpine linux and 8.0.2 works fine.
