stage.nix: revert deletion of gcc.abi="elfv2" from 82ff1f5#191436
Conversation
Commit 82ff1f5 in #182807 removed two lines from stage.nix which were responsible for making sure the `gcc` for `pkgsStatic` on powerpc64 was built with the `--with-abi=elfv2` flag. Unfortunately this causes build failures for `pkgsCross.ppc64.pkgsStatic`, as reported here: #182807 (comment) This commit reverts the deletion. Unfortunately ugly kludges like this are necessary because nixpkgs' `lib/systems/` doesn't understand the difference between a libc and an abi. So we have no clean way to tell nixpkgs "musl on big-endian powerpc64 always uses the ELFv2 ABI" -- it thinks that musl is an ABI. Until that gets fixed there is no better way to add the flag.

There was a problem hiding this comment.
Tested it with nix build 'github:NixOS/nixpkgs/pull/191436/head#pkgsCross.ppc64.pkgsStatic.busybox' at it works great again. Sorry about the flop, I somehow thought that musl would auto-select the ELFv2 ABI, but forgot to test it...
