GHC 9.2.1-rc1 needs to run xattr in ghc.mk unconditionally. The fix for
this and support for the XATTR environment variable have only been added
to the GHC 8.10 series so far.
The only big change is required for darwin since GHC 8.10.5 now
runs xattr in the install phase on darwin:
* 11e1dcde0d
* ec451cac39
Unfortunately, it uses the host /usr/bin/xattr by default which is
present in the build due to a lack of sandboxing on darwin. That xattr
version however still requires Python 2.7 whereas Python 3.8 is in PATH
in our build. We solve this by setting the XATTR environment variable.
We can't use python3Packages.xattr since GHC expects Apple's fork of
xattr which provides some extra flags to utilize.

This reverts commit 36628e6e04.
As it turns out this wasn't caused by the update from python 3.8 -> 3.9,
but the underlying issue affects both python version (it seems that LTO
is at fault currently). Will have to be fixed elsewhere, reverting.
seems like python39 currently fails to build with musl as libc
https://github.com/NixOS/nixpkgs/issues/131557. As a workaround, we can just
build the musl GHCs using python38 like we have been in the past (the python 3.8
-> 3.9 update being a more recent development).
This addresses the fact that `ghc865Binary` segfaults on musl
(see #118731) because of the glibc+musl mix used in there.
With the previous commits, `ghc8102Binary` was changed to use
the musl-based bindist from GHC HQ instead, which works.
With this change, all nix Haskell compilers builds on musl:
NIX_PATH=nixpkgs=. nix-build --no-link --expr 'with import <nixpkgs> {}; { inherit (pkgsMusl.haskell.compiler) ghc884 ghc8104 ghc901 ghcHEAD; }'
ghc8102Binary doesn't build on hydra on arm since it exceeds the maximum
output size. This change works around this issue by using the minimal
version of that compiler instead.
* ghcHEAD: bump to 8.11.20200403
* ghcHead: reduce diff vs. 8.10.1
dontAddExtraLibs was removed by accident (IMO) in ea19a8ed1e
* ghcHEAD: add ability to use system libffi
- enable nixpkgs' libffi
- minimise diffs against 8.10.1
- remove patching
* remove configure warning about --with-curses-includes
configure: WARNING: unrecognized options: --with-curses-includes
The 8.4.x version of ghcjs hasn't compiled successfully
in ages, so I reckon it's unused. The even older code
in pkgs/development/compilers/ghcjs is unused entirely;
it's not even referenced in Nixpkgs.
