[OE-core] [PATCH] kernel-arch.bbclass: Allow 'baremetal' CPUs

[Juro Bystricky]

Avoid "ERROR: cannot map <cpu> to a linux kernel architecture"
Not being able to map a CPU to a kernel architecture should not be treated as
an error when building baremetal toolchains for CPU <cpu> which does not have
a kernel source tree.

Rather then individually enumerating each additional (baremetal) CPU, allow them all.
This way the kernel-arch.bbclass does not need to be modified each time a support
for a new baremetal CPU is added.
