Don't pull in x86emu from a foreign directory anymore. This

produced numerous problems in the past, including the fact that
x86emu doesn't work in v3 anymore even though it lives in the v3
repository.

Since this is a cross-repository move, keeping the history in the v2 tree 
would make life hard for everone. So check the v3 repository for x86emu history
since the merger. The his commit is based on an svn export of r1175 of the
coreboot-v3 repository.
