Revert "kernel/kernel-arch: Explicitly mapping between i386/x86_64 and x86 for kernel ARCH"
This reverts commit 8d310b24927d0f348fb431895f0583733db2aad0. That commit completely breaks KBUILD_DEFCONFIG because it relies on $ARCH to match between the target OE arch and the kernel subdirectory containing the defconfigs. In the kernel all defconfigs for everything x86-based (including x86_64) is stored in dir arch/x86/configs/ kernel-yocto.bbclass correctly searches for all the defconfigs inside ${S}/arch/${ARCH}/configs/${KBUILD_DEFCONFIG} Commit 8d310b249 makes it search in wrong places and _only_ if you define TARGET_ARCH = "athlon" will it search x86 which is nonsensical. The commit further adds an if clause to hack the mungled kernel arches back to their original values (ugh) in do_shared_workdir which is run after do compile, but of course the build breaks before that in do_kernel_metadata because of the KBUILD_DEFCONFIG mentioned above (so that hack is useless). Please fix that corner case bug in another way which does not completely screw up the kernel arch mapping & defconfig logic. If 64bit configs are generated in the kernel for 32bit machines because the host is asked, then it it a bug in the kernel, it is of no use to hack around it in OE.
