It stayed broken because 99.9% of the people who install tcc also install gcc/clang, which happen to pull in the required dependency :)

Copy/paste the fix from gcc's template:
```
case "$XBPS_TARGET_MACHINE" in
        *-musl)  depends+=" musl-devel";;
        *)       depends+=" glibc-devel";;
esac
```

and submit a pull request (unless it's troublesome for some reason)
