Describe the bug

Cross-compilation to armv7l-unknown-linux-gnueabihf is broken on HEAD

Steps To Reproduce

  1. build pkgsCross.armv7l-hf-multiplatform.lix with a Lix HEAD overlay

Expected behavior

The cross-compiled Lix package should build

nix --version output

nix (Lix, like Nix) 2.92.0-dev-pre20250112-38dd196

Additional context

pretty much a bug in boost interacting badly with clang: https://github.com/llvm/llvm-project/issues/120871

our packaging should probably work around that by throwing -fno-integrated-as into NIX_FLAGS_COMPILE or something like that (wouldn't want to shove that into meson since it's clearly not our original problem)

Ultimately this breakage is much bigger than us and needs to be addressed in nixpkgs by patching boost or upgrading it assuming they got a release out. There's a workaround as mentioned that can be applied via overrideAttrs in the interim if needed.

The user experience is: I add the Lix overlay and it breaks.
Can we not build it with gcc on targets where clang is broken?

we're always building with clang instead of gcc because gcc straight up miscompiles lix. gcc has open bugs about this behavior, but isn't doing very much to fix it.
