bug#45776: Bug? Haskell GHC wont' work since ghc@8.6?

[yasu]

This one ought to be very simple to solve (or at least confirm).   Does
anyone use Haskell daily?

I am a very casual user of Haskell (GHC) and when I tried to compile
something just now, I noticed that it can't even compile the simplest
possible program..., unless I downgrade to ghc@8.4 or lower. Newer
versions, including ghc@8.6.5, didn't work, throwing the error message
below instead.

~/co/haskell-tiny-intro/exercise (master *)$ cat a.hs
main = putStrLn "a"

~/co/haskell-tiny-intro/exercise (master *)$ ghc a.hs
Linking a ...
.gcc-wrapped: error: unrecognized command line option '-no-pie'
`gcc' failed in phase `C Compiler'. (Exit code: 1)

Cheers,
Yasu
