gnu: chez-scheme-for-racket: Fix supported systems.
This commit fixes the treatment of systems like "powerpc-w64-mingw32",
where the combination of architecture and kernel is not supported, even
though both are supported in other combinations. The build failure fixed
in b8fc9169515ef1a6d6037c84e30ad308e5418b6f highlighted this problem:
see also <https://issues.guix.gnu.org/54292#6>. The correct support
status is specified by '%chez-features-table', which was added to
improve 'chez-upstream-features-for-system': this commit uses it to fix
the repair.
Once the issues in <https://racket.discourse.group/t/950> are resolved,
'chez-scheme-for-racket' and 'racket-vm-cs' will be able to run even on
systems for which native code generation is not supported. It's not
clear what behavior would be useful from 'nix-system->chez-machine':
since the current implementation is flawed and easy to misuse, we remove
it for now, replacing the remaining uses with
'racket-cs-native-supported-system?'.
* gnu/packages/chez.scm (nix-system->chez-machine): Remove it.
(racket-cs-native-supported-system?): New variable.
(chez-scheme-for-racket)[supported-systems]: Use it.
* gnu/packages/racket.scm (racket-vm-for-system): Likewise.
