The generic one doesn't work on ARM, and it's supposed to override the
generic one. It seems that ddd588b5dd55f14320379961e47683db4e4c1d90
causes the generic one to be pulled in due to a reference to __show_mem()
which then causes show_mem() to be defined twice.
The change in lib/show_mem.c needs to also be ported to ARMs own version.
