[PATCH 08/13] arch: maintain Linux kernel and mkimage ARCH mapping in Kconfig

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

How barebox calls the architectures it supports differs from both the
names used in the Linux kernel and in mkimage.

For easier interoperability with the two, especially in scripts, add
config options that hold the relevant names.
