I had build once a coreboot image for a Intel G41 board. Then i liked to build for an other Intel G41 board. I first removed the config: rm .config* then i ran again 'make menuconfig' chose the other Intel G41 board and ran 'make'.
I got this error:

I then removed the config with rm .config* ran again 'make menuconfig' and chose again the board that i was able to build an image before some minutes with a warning ( https://mail.coreboot.org/pipermail/coreboot/2018-August/087162.html ). Then i ran 'make'. Now i also get for that board the issue i have copied above. This Compiling IASL src/fw/ssdt-misc.hex failed again. But it was probably working before because i had got an image.
