make bug: make crashes on linking libc.so

[Frank Pettit]

Hello,
I am trying to compile glibc 2.3.2 on Linux Mandrake, and have found
that the 'make' command crashes at the step where libc.so is linked,
due to undefined references into pthreads. I want to emphasize that I
HAVE downloaded the linuxthreads add-on and untar'ed it in the root of
my glibc source tree, and I configured glibc with option
'--enable-add-ons=linuxthreads'.

By looking through the source code, I find that the undefined
references refer to global variables in the file pthread.c, which is
in subdirectory linuxthreads. I looked through the output of the
'make' command, and pthread.c is not compiled anywhere, so of course
references to it will be undefined, but I don't know how to fix this
problem.

My attempt to compile is all standard except that I define CFLAGS with
option -DFLOATING_STACKS. Below is info on my OS, setup,
configuration, the make command that crashes and the error output.

** ARCHITECTURE / OS INFO **
