I'm using nixpkgs' gcc as a cross-compilation linker, and unfortunately, it's causing maturin's wheel repair to fail with the following error:
After some investigation, it appears that, when trying to autodetect the sysroot, maturin runs
$CC --print-sysroot. Unfortunately, the version ofgccused by nixpkgs will simply print an empty string in this case, causing the build to fail. With this patch, however, it all works and generates a working wheel.
