removed.

I should remove all the neon stuff, it's bitrotted anyway.

ok, I think I found it. This is a change made by YunQiang Su to build libgnatprj
and libgnatvsn as target libraries, pulling in a dependency
Makefile.def:
+dependencies = { module=all-target-libgnatprj; on=all-target-libiberty; };
Find out how to define this conditionally?
Anyway, please check if this is the real cause. attaching a hack which should
work around that.
