In short, there is no way to either enable libthread_db at _start time for a
static binary, or find the appropriate time to initialize it later.  I propose
allowing it to initialize, and then reporting the "creation" of the first thread
once the pthreads library is initialized.

The patch is here:

  http://sourceware.org/ml/libc-alpha/2006-03/msg00014.html

Without a fix for this problem, GDB can not debug static executables which use NPTL.

I'm responsible for nptl_db and recall some poking related to this in the past.
I'll look into it, but it won't be before June 5 as I'm leaving for vacation now.

Roland, did you ever get a chance to look at this?  Another user just reported a
similar problem on gdb@.

Sorry, still back burner.  It will be a little while longer before I get to my
libc backlog.

Roland checked in an NPTL patch for this and I fixed gdb.
