My patch for this is at 
<https://sourceware.org/ml/libc-alpha/2016-11/msg00313.html>.  I'm not 
concerned with which fix goes in as long as this does get fixed.

My other fixes for build-many-glibcs.py are 
<https://sourceware.org/ml/libc-alpha/2016-11/msg00314.html> (ia64) and 
<https://sourceware.org/ml/libc-alpha/2016-11/msg00584.html> (nios2).  
With GCC 6 branch (which seems to give the cleanest results in my 
testing), I still get elf/check-execstack and elf/check-textrel failures 
for hppa, and elf/check-execstack failing for ia64, which I hope 
architecture maintainers might look at (if elf/check-execstack is hard to 
fix for an architecture, XFAILing as I did for MIPS with an appropriate 
explanatory comment seems reasonable).  (There are also build failures for 
ColdFire and MicroBlaze because of compiler issues.)

(I hope to extend build-many-glibcs.py for use as a bot to watch for 
regressions.  If the check stage fails because of existing test failures, 
that can hide other tests starting to fail.  So clean compilation tests 
for all architectures are desirable.)
