This closes#79441.
ghcWithPackages is using `ghc-pkg recache` to build its package
database. By doing so, it overrides the `package.cache[.lock]` files.
Details are unclear, but GHC 8.10 changed a bit the behavior.
Previously, it was unconditionally replacing the files by new ones. Now
it tries to open (for modification) the files. These files are symlinks
to another nix derivation, which is hence read-only.
This commit removes the files before running `ghc-pkg recache`, hence it
will just write the new files.
Tested with `haskellPackages.ghcWithPackages` (i.e. GHC 8.8) and
`haskell.packages.ghc8101.ghcWithPackages` (i.e GHC 8.10) with the
following nix file, at the root of the nixpkgs repository:
```
with import ./. {
overlays = [
(
self: super: {
haskellPackages = super.haskell.packages.ghc8101.override {
overrides = selfh: superh: {
th-lift-instances = super.haskell.lib.doJailbreak superh.th-lift-instances;
th-expand-syns = super.haskell.lib.doJailbreak superh.th-expand-syns;
th-reify-many = super.haskell.lib.doJailbreak superh.th-reify-many;
th-orphans = super.haskell.lib.doJailbreak superh.th-orphans;
haskell-src-meta = super.haskell.lib.doJailbreak superh.haskell-src-meta;
};
};
}
)
];
};
haskellPackages.ghcWithPackages(p:[p.PyF])
```
This will test with GHC 8.10. Comment out the `overlays` to test with
GHC 8.8.
* 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 patch phase runs after the build phase. Which means than when
using an override to override both 'conf' and 'patches' to provide
a custom config file and apply some patches, it doesn't work:
- first the patches applied (optionally changing config.def.h)
- then preBuild is run which overrides config.def.h with the user
supplied one (effectively cancelling previously applied patches)
By copying the config file in the prePatch phase instead, changes
are kept and applied in order.
Unfortunately, the upstream changelog consists of just the following:
* Update to the Reiner-SCT repository rev cyberJack@1374
This is not very helpful since I haven't found a public SVN (I assume,
since it's using integer revisions) repository, so I decided to diff the
tarball against the old one, here's what I've found:
* No longer ship generated files from autotools
* Add support for REINER SCT cyberJack comfort PL
* Add support for tanJack USB
* Allow to override secoder information
* Lots of whitespace and coding style changes
As mentioned above, the autotools-generated files are no longer shipped,
so I've added autoreconfHook to nativeBuildInputs.
I also verified the source tarball using the upstream hashes found here:

- update to the latest commit in git repository
- use mkDerivation for qt applications
- original repo disappeared from github; use the one from gitlab
