arm: fix architecture detection
There are many variants of arm and it seems to be impractical to
add them all to the arches array. Instead just match on the
leading "arm" portion of the utsname.
I have made this specific to arm for now, as I'm not sure what
fallout might occur if it was made more generic. e.g. arch ppc
matching utsname ppc64 is a concern.
Based on variants of this patch submitted by Andrea Adami and
Marc Andre Tanner, and feedback from Magnus Damm.
