[ Jeff, when people try to link 64-bit pthread applications on
  sparc on Niagara or UltraSPARC-III boxes, they get link errors
  because glibc doesn't set the symbol versions correctly in
  libpthread.so in these cases... ]

The bug here is an error in the regular expressions used
in linuxthreads/shlib-versions and nptl/shlib-versions

They both use "sparc64-.*-linux.*" but it should be using
"sparc64.*-.*-linux.*"

The other shlib-versions files in the glibc tree get this
right.

Here is a patch against the current dapper glibc tree.
