cross-x86_64-w64-mingw32-gcc-stage1 log

I'm trying to build the x86_64-w64-mingw32 toolchain built on my system to compile the Windows/WINE component of github.com/falkTX/carla. But it fails while emerging cross-gcc-stage1.

After running either of the following commands:

```
# crossdev -S --target x86_64-w64-mingw32
# crossdev -t x86_64-w64-mingw32
```

the error message returned is:

```
error: gcc failed :(
```

I have the following in /etc/portage/package.accept_keywords:

```
cross-i686-w64-mingw32/mingw64-runtime ~amd64
cross-x86_64-w64-mingw32/mingw64-runtime ~amd64
```

I have configured crossdev to use its own, separate overlay.

I've also tried `crossdev -C` before trying again, and that didn't fix the issue.

As requested by the error message, appropriate logs have been attached for a few different targets that have all failed. I'll be happy to provide further information if I'm able. Thank you for taking a look at this! It will be extremely beneficial to me personally if we can work this out.

Probably a fallout from https://gitweb.gentoo.org/proj/crossdev.git/commit/?id=7283a01fc3dd7523793c28d8acd04ce7fd049389

Try 'crossdev --with-headers -t x86_64-w64-mingw32' as a workaround.

    crossdev: reenable --with-headers for mingw targets
    
    gcc can't build libgcc2.c on --without-headers setup.
    Needs more investigation.
