Description of problem:
glibc-devel contains a symbolic link
/usr/lib/librt.so.1 -> librtkaio.so
which points to a non-existing file

Version-Release number of selected component (if applicable):
glibc-devel-2.5-3.i386.rpm

How reproducible:
100%

Steps to Reproduce:

root@computer:/etc# rpm -U /fedora-core/6/i386/os/Fedora/RPMS/glibc-2.5-3.i686.rpm
 /fedora-core/6/i386/os/Fedora/RPMS/glibc-devel-2.5-3.i386.rpm --force

root@computer:/etc# rpm -V glibc glibc-devel

root@computer:/etc# ls -la /usr/lib/librt*
-rw-r--r-- 1 root root 52128 Oct  8 17:10 /usr/lib/librt.a
-rw-r--r-- 1 root root 59038 Oct  8 17:10 /usr/lib/librtkaio.a
lrwxrwxrwx 1 root root    20 Dec 31 09:42 /usr/lib/librt.so -> ../../lib/librt.s
o.1
lrwxrwxrwx 1 root root    12 Dec 31 09:42 /usr/lib/librt.so.1 -> librtkaio.so

root@computer:/etc# /sbin/ldconfig 

root@computer:/etc# ls -la /usr/lib/librt*
-rw-r--r-- 1 root root 52128 Oct  8 17:10 /usr/lib/librt.a
-rw-r--r-- 1 root root 59038 Oct  8 17:10 /usr/lib/librtkaio.a
lrwxrwxrwx 1 root root    20 Dec 31 09:42 /usr/lib/librt.so -> ../../lib/librt.s
o.1

root@computer:/etc# rpm -V glibc glibc-devel
missing     /usr/lib/librt.so.1

Actual results:
before ldconfig call:
- librt.so.1 is a broken link
after ldconfig call
- librt.so.1 is missing (deleted by ldconfig)

Expected results:
glibc-devel should contain the correct symbolic link and after ldconfig the
glibc-devel package should be consistent with the file system (rpm -V glibc-devel)
