Build fails with 'nvramcui' as second payload

It fails with:

After changing mpreferred-stack-boundary to 3 in
heads/build/coreboot-4.8.1/payloads/libpayload/arch/x86/Makefile.inc

it fails with:

Unfortunately, I can't find the source of this error.
Any suggestions?

[MrChromebox]

what's the point of building secondary payloads since Heads can't launch them?

@MrChromebox those are ELF binaries. Why couldn't we launch them? (Not from menu now, but from Head's recovery shell?)

[Siproqu]

I have built the nvramcui in a standalone coreboot build (i386), but couldn't run it. The kernel doesn't accept it and the elf file is interpreted as a shell script.
Heads is built as an i386 kernel, isn't it?

[tlaurion]

@Siproqu coreboot only is I386

[Siproqu]

As I do not have the time to test it again and the settings applied by nvramcui won't change frequently anyways, here is a workaround.
Obviously the linked patch file of the workaround has to be adjusted for the user's needs.
