The idea is cabal-install / `./Setup` will know about C headers and libs, but the C compiler itself will not directly. - nativeGhc -> depsBuildBuild - Setup.hs libraries -> nativeBuildInputs - other tools -> nativeBuildInputs - libraries -> (propagated)NativeBuildInputs Also, I'm trying to start the process of smoothing over the differences between our builder and shell env. - Everyone gets tools - Everyone only accesses C through Cabal
Use the clang sierrahack stdenv instead
Also make sure that Setup.hs dependencies are kept disjoint

OK the later commits I added aren't really appropriate at this time, as I need to dust off my darwin hack first and make it appropriate for |

Will revisit after #26799, which is very close. |

Motivation for this change
The idea is that one can do
cabal configure $NIX_CABAL_FOREIGN_FLAGSwhich ensure that Cabal knows about C headers and libs, but not the c compiler itself.Also, I'm trying to start the process of smoothing over the differences between our builder and shell env.
-systemor-LflagsI'd like to go even farther and
ghcWithPackages--with-package-dbto./Setup/NIX_CABAL_FOREIGN_FLAGSghcWithPackages, OTOH, should use acc-with-packages, for a completely (cabal-install or stack)-free persistent environments. Granted, I don't know why one would want to not use either of these tools, but ifghcWithPackagescontinues to exist with the plan above, this gives it its own clear-cut and distinct niche.Things done
