 division by zero bug). Problems with glibc.

Thanks for helping to track down this bug. Since the problem occurs only 
with a few Linux kernel versions and affects Emacs only when doing CPU 
profiling, it doesn't seem worth spending time to try to patch Emacs to 
work around the bug. So I installed the attached patch into emacs-26's 
etc/PROBLEMS file to warn users about the problem, and am closing the 
Emacs bug report.
