README: Delete obsolete i386 info + update arch/i386/ paths
Support for i386 was removed in v3.8, delete the paragraph that says
processor types above 386 won't work on that architecture. It's obsolete
information and potentially confusing. Also change a couple of
"arch/i386/" paths to one that exists now, using "arch/x86/" instead.
