It's one more thing to track when to remove when the minimum GCC version 
for building glibc increases.  (We have such a comment on the use of 
--disable-libcilkrts.  We ought to have one on the use of 
--disable-libmpx.  If we used --enable-initfini-array, that should have 
such a comment as well.)
