John Ericson f110a182a6 stdenv: Fix overriding + overrideAttrs ... The old stdenv adapters were subtly wrong in two ways: - `overrideAttrs` leaked the original, unoverridden `mkDerivation`. - `stdenv.override` would throw away any manually-set `mkDerivation` from a stdenv reverting to the original. Now, `mkDerivation` is controlled (nearly directly) via an argument, and always correctly closes over the final ("self") stdenv. This means the adapters can work entirely via `.override` without any manual `stdenv // ...`, and both those issues are fixed. Note hashes are changed, because stdenvs no previously overridden like `stdenvNoCC` and `crossLibcStdenv` now are. I had to add some `dontDisableStatic = true` accordingly. The flip side however is that since the overrides compose, we no longer need to override anything but the default `stdenv` from which all the others are created.		2021-08-18 17:22:50 +00:00
