It seems to keep failing on all sub-directories of utils/. I manually changed 

utils/*_dist-install_DEP_EXTRA_LIBS = rt util dl gmp m rt dl pthread 

and the stage2 compiler built successfully after that. Has anyone else faced this problem building the utils/* in commit 1757dd8? If so, I'll submit a patch that adds on the 'pthread' to DEP_EXTRA_LIBS in the utils/ directory.

Hi GHC Devs,

Refer https://github.com/NixOS/nixpkgs/issues/14333 for a problem I was having when building with nix. The interesting part is that if I add an extra flag -optl-lpthread manually, the error goes away and the build succeeds. My question is why the build system didn't add the -optl-lpthread flag when libpthread was a requirement for that particular build? 

Thanks,
