commit 39b1f6172a2f9ddc74a8f82d6e84dd13b22dbaf2
Author: Peter Collingbourne <pcc@google.com>
Date: Wed May 15 20:28:08 2013 +0200
Move _obstack_compat out of common
it is impossible to create an alias of a common symbol (as
compat_symbol does), because common symbols do not have a section or
an offset until linked. GNU as tolerates aliases of common symbols by
simply creating another common symbol, but other assemblers (notably
LLVM's integrated assembler) are less tolerant.

Avoid .symver on common symbols [BZ #21666]
The .symver directive on common symbol just creates a new common symbol,
not an alias and the newer assembler with the bug fix for
