Arch Linux

Description: Hello. I tried this morning to build one of my AUR package - dosbox-x-sdl2-git- and when configure try to see if there is a working c compiler, I got this error message:

```
checking whether the C compiler works... no
configure: error: in `/home/fred/dosbox-x-sdl2-git/src/dosbox-x':
configure: error: C compiler cannot create executables
```

I tried with midnight commander, and here is the output log:

```

See `config.log' for more details
```


Additional info:
* gcc 10.2.0-5

Steps to reproduce:

Just update to gcc 10.2.0-5 and try building any software. Configure will tell there is no c compiler available.
