Wait wait wait, I know what this is, it's not a bug in glibc.  The stat 
system call interface was updated to use newfstatat and it just looks 
like fakeroot does not recognize it yet.  So fakeroot needs to be 
updated to recognize and override that system call to return 0 (and 
emulate root privs) instead of the UID.
