[PATCH] uml: fix processor selection to exclude unsupported processors and features
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).
