It guards `asm (".hidden\t__dso_handle");' in crtstuff.c.  I guess

Fixing it probably only requires doing the following.  My linux box's
gas doesn't support .hidden and I don't know of any testcases anyway.
So I can't test it or claim it works.  But its the same action taken
before your patch, so...  OK to install as an "obvious" fix to your
last patch?
