arch: add BR2_READELF_ARCH_NAME hidden config option
This config option corresponds to the string returned by readelf for the "Machine" field of the ELF header. It will be used to check if the architecture of binaries built by Buildroot match the target architecture. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>2017.05.x
