it was reason for workaround rules already, and it's somewhat ugly:

util/x86emu is the only part of coreboot that is linked into coreboot

It's not a utility and it does not really belong where it lives.

---> svn mv util/x86emu src/devices/oprom

plus necessary Makefile changes to get it building again
