Comment:
All failed checks begin with:
```
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-musl/9.2.0/../../../../lib/crt1.o: in function `_start_c':

/builddir/musl-1.1.23/crt/crt1.c:18:0: error:

     undefined reference to `main'
```

As far as I know, this is caused by missing ghc or missing stack hostmakedependencies.
