Bootstrapping from scratch with the patch you sent me still shows the
problem.  I will try with the patch you sent to Andreas.

As I mentioned in the PR, for AIX one can reproduce the problem by
compiling libobjc/linking.m.  That is a fairly small file and produces
invalid assembly due to ctor priority of -1.
