Makes UML compile on any possible processor choice. The two problems were:
*) x86 code, when 386 is selected, checks at runtime boot_cpuflags, which we do
not have.
*) 3Dnow support for memcpy() et al. does not compile currently and fixing this
is not trivial, so simply disable it; with this change, if one selects MK7
UML compiles (while it did not).
Merged upstream; I'm resending since spam filters blocked my previous mail.
