bug#62226: bash-minimal fails to build on x86_64-w64-mingw32

[Ekaitz Zarraga]

Any package that uses `bash-minimal` to build in mingw (all of them?) fails when trying to build `bash-minimal` with the following error:

```

```

I'll investigate but I don't think I'll reach far on this one.

I already tried removing the offending lines from the `config.h` but other errors appear (how surprising :) )

Thanks all,

Hi,

Adding:

```
"ac_cv_header_sys_socket_h=no"
```

To configure flags in the case the target is mingw solves the first issue, but more issues appear.

I have no enough knowledge about autotools to dig into this much further but it looks like we are finding wrong stuff in the configure step:
