GHC since 8.10 build fails on Debian armel
GHC 8.10.x builds fail on 32-bit ARMv5 without hardfloat.
8.10.4 with LLVM 11: https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=armel&ver=8.10.4-1%7Eexp1&stamp=1613305029&raw=0
8.10.6 with LLVM 12: https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=armel&ver=8.10.6-1%7Eexp2&stamp=1629838287&raw=0
I also tried 8.10.6 with -mattr=+soft-float,-fp16,-vfp2,-vfp2sp,-vfp3,-vfp3sp,-vfp3d16,-vfp3d16sp,-vfp4,-vfp4sp,-vfp4d16,-vfp4d16sp,-fp-armv8,-fp-armv8sp,-fp-armv8d16,-fp-armv8d16sp,-fullfp16,-neon,-crypto,-dotprod,-fp16fml,-fp64,-d32,-fpregs,+strict-align and got this
