Strange "make regen-ulps" result on x86_64

[Joseph S. Myers]

These errors look rather like the tests got run with an old installed 
version of glibc.  First step, make sure your source tree is clean, remove 
your build tree and try configuring and building afresh, before looking 
at exactly what shared libraries are opened in the regeneration process 
if the problem persists.
