Thanks a lot for this.

Looking at the code, the bug seems to be in
https://sources.debian.org/src/ghc/8.4.4+dfsg1-2/debian/patches/llvm-arm-unknown-linux-gnueabi.patch/

ARM1136JF-S is ARM11, which is ARMv6.

arm9e would be correct here instead of arm1136jf-s.

Due to the static-only nature of the ghc ecosystem the fix would then 
require a complete rebuild of all Haskell packages on armel, but with
the buildds otherwise mostly idle now this should be finished within
2-3 days.
