[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).
