[OE-core] [PATCH] map_kernel_arch: x86 sub-architectures

[Sergey Matyukevich]

Suppose we build software for x86 targets on x86 build hosts. There are use-cases
when it is not enough to specify x86 as a kernel architecture. It is necessary
to go one step further and to specify proper x86 sub-architecture (i386 or
x86_64) of the target system.

This patch modifies kernel-arch.bbclass in the following way:
 - adds x86_64 to the list of valid architectures
 - differentiates between i386 and x86_64 sub-architectures in map_kernel_arch
