Hi GHC Devs,

Refer 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?
