On some archs, it fails with:
```

```
I wonder if I need to do something like:
```
case "${XBPS_TARGET_MACHINE}" in
    aarch64*)
    <compile options>
    ;;
    armv6l* | armv7l*)
    <compile options>
    ;;
esac
```
in `do_install` as, for those archs, the build flags / options have issues with the `X11` headers? I'm not too familiar with the archs that it's failing on. I wonder if it's also worth just saying `archs="x86_64* i686"`.
