Mark wayland broken on Darwin/Big Sur

[edude03]

Motivation for this change

ZHF: #122042, ping @NixOS/nixos-release-managers

As mentioned in the comment, it seems like in the work @thefloweringash & co did to get nixpkgs working on Big Sur means that apps that need GCC to build no longer work (like Wayland). Maybe there is a way to bring support back, but at least for now it's broken.

On a side note, is there a way to check if stdenv is using clang or gcc? maybe a better check would be to check for clang instead.

Also, it does seem like GCC does work on big sur now https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97865 so maybe we can fix this.

To comply with CONTRIBUTING.md please have the commit message name be of the format

<pkg-name>: <subject-line>

for more examples, please look at https://github.com/NixOS/nixpkgs/blob/master/.github/CONTRIBUTING.md#submitting-changes

in your case, the commit message should be:

wayland: mark broken for darwin

also, in the commit message, can you add some details. The code comment should suffice :)

[jonringer]

Do you mind squashing the two commits?

Please follow CONTRIBUTING.md and manual#submitting-changes-making-patches and squash the fix-up commits.

git rebase -i is a powerful command which achieves this, I created a small video demonstrating it's use here. A more indepth text tutorial can be found here

LGTM

thanks @edude03

Thanks @jonringer - although I do know how to rebase, I still really appreciate you linking to resources in case I didn't. I think it's really welcoming to new members of the community

I had someone ask once, so just made a saved reply explaining it :)

Does this still apply? I was able to compile wayland without issue.
