[coreboot] Kconfig and util/

[Myles Watson]

How do you include anything in util in a build?  It looks like we
prepend src/ in our makefiles.

I was trying to add support for choosing between the emulators, but
none of them build for me.  I did however get it to erase my biosemu.c
file with make clean :)

from:util/x86emu/Makefile.inc:
obj-$(CONFIG_PCI_OPTION_ROM_RUN_X86EMU) += biosemu.c

I think this should be biosemu.o

At least I know the file is being read.

Thanks,
Myles
