[coreboot] ramstage/x86emu doesn't build

[Martin Kepplinger]

Hi,

Before I dig in without knowing the code: x86emu currently ( 
0987e43aa05bfbafbfdd4952638b79a5084369f8 )
doesn't build:

In file included from src/device/oprom/x86emu/x86emui.h:65,
                  from src/device/oprom/x86emu/debug.c:40:
src/device/oprom/x86emu/debug.c: In function 'x86emu_dump_regs':
src/device/oprom/x86emu/debug.h:46:22: error: implicit declaration of 
function 'printk'; did you mean 'printf'? 
[-Werror=implicit-function-declaration]
  #define printf(x...) printk(BIOS_DEBUG, x)
                       ^~~~~~
src/device/oprom/x86emu/debug.c:366:5: note: in expansion of macro 
'printf'
      printf("\tAX=%04x  ", M.x86.R_AX );
      ^~~~~~

I append the config. Also, there's noone in MAINTAINER for it, and 
appearently it's not build-tested :(

thanks
