Description of problem:
According to the packaging guidelines [1] packages for F17+ must not place files or directories to /bin, /sbin, /lib or /lib64:
> In addition, Fedora packages MUST NOT place files or directories
> in the /bin, /sbin, /lib or /lib64 directories. Instead,
> the /usr/bin, /usr/sbin, /usr/lib, and /usr/lib64 directories must be used.
> Packages must assume that /bin, /sbin, /lib, and /lib64 are symbolic
> links to the /usr/bin, /usr/sbin, /usr/lib, and /usr/lib64 directories,
> respectively. 

But glibc still uses these directories and I cannot find any exception for this.

Version-Release number of selected component (if applicable):
glibc-2.16.90-16

How reproducible:
Always

Steps to Reproduce:
1. rpm -ql glibc | grep '\(^/s\?bin\)\|\(^/lib\(64\)\?\)'
  
Actual results:
Files are placed into /bin, /sbin, /lib, and /lib64

Expected results:
Files should be placed into /usr/bin, /usr/sbin, /usr/lib, and /usr/lib64
