PATCH: Do not create __exidx_{start,end} for ld -r

[Mark Mitchell]

The armelf.sh configuration is presently creating the
__exidx_{start,end} even when not relocating, e.g., when doing "ld
-r".  That's incorrect; these symbols should only be defined when
creating a shared library or executable.

OK to commit?
