[Bug libc/10072] New: 2.9.90 (2009-04-14) : ldconfig creates wrong links for librt, libdl, libpthread

TEST CASE:
~~~~~~~~~~

After a checkout from CVS, build, and install, of glibc-2.9.90 of 2009-04-14, 
under linux-2.6.30-rc1 for x86_64, with 
configure args:
 
$ ../configure --prefix=/usr --libdir=/usr/lib64 --enable-shared \
 --enable-tls --enable-threads=posix --enable-multilib  \
 --build x86_64-pc-linux-gnu --host x86_64-pc-linux-gnu \
 --target x86_64-pc-linux-gnu

After glibc built OK, under :
 linux    : 2.6.30-rc1 (linus + tip_x86 GIT of 2009-04-10)
 gcc      : 4.3.4      (20090410)
 binutils : 
I did:

$ make install install_root=/tmp/glibc-2.9.90-2009-04-14
$ cd /tmp/glibc-2.9.90-2009-04-14; tar -cpf - . |
  bzip2 > ${DISTRIB}/glibc-2.9.90-2009-04-14.tar.bz2

Then rebooted into another OS and unpacked the installation archive
into the OS where I built glibc.

Then I did chroot to the new glibc system, and did:
$ ldconfig

After that, EVERY command got a SIGSEGV, because there were some ancient
artifacts of a mistake in /lib64 ; going out of the chroot and into 
the new glibc system's /lib64, showed:

$ ls -l librt.so.1 libdl.so.2 libpthread.so.0
lrwxrwxrwx 1 root root 15 Apr 14 18:44 libdl.so.2 -> libdl.so-2.8.so
lrwxrwxrwx 1 root root 20 Apr 14 18:44 libpthread.so.0 -> libpthread.so-2.8.so
lrwxrwxrwx 1 root root 15 Apr 14 18:44 librt.so.1 -> librt.so-2.8.so

These old *.so-2.8.so libraries were over a year old; 
the ldconfig from the glibc-2.9.90 of 2009-03-20 did NOT think these
artifacts were current libraries, while the new ldconfig DID -
this IMHO is a bug.
After removing *.so-2.8.so from /lib64, glibc-2.9.90 of 2009-04-14 passed
all tests OK.
