[coreboot - Bug #527] Can't compile coreboot on Arch Linux

[Peter Daru]

Issue #527 has been updated by Peter Daru.

Sorry if this doesn't fit here. I thought this is similar if not same issue as op's one.

I was following [doc tutorial](https://doc.coreboot.org/tutorial/part1.html) for qemu x64 and also couldn't compile. I run fully up to date installation (apart from kernel itself). Turns out doing `$  make clang CPUS=$(nproc)` and then `$ make` I was able to compile.

This is what I got following tutor:

----------------------------------------
I want to compile coreboot for my Gigabyte GA-H61M-DS2 mainboard, but I only found a short guide for this board at this site: https://www.iot-tech.dev/full.php?ar=166
After downloaded the coreboot git repository, It gave me this error:
``` shell

```
And I'll put my config file on here.
Any help ?
