binutils: Inform binutils that armv5e really is valid!

Browse Source 
A comment in the binutils sources indicate that it should support all of the
-march= parameters that gcc supports.  The tune validations noted that
gas failed on -march=armv5e.

It is not yet clear to me if this patch belongs upstream or not.

Add the armv5e architecture to binutils
Binutils has a comment that indicates it is supposed to match gcc for all of
the support "-march=" settings, but it was lacking the armv5e setting. This
was a simple way to add it, as thumb instructions shouldn't be generated by
the compiler anyway.
