how to *explicitiy* de-activate linuxthreads?

[Robert P. J. Day]

  i'm trying a build with glibc-2.5 which has no built-in support for
linuxthreads, and i've specifically set

  GLIBC_ADDON_OPTIONS="=nptl"

to get NPTL instead.  and yet, one of the first things that happens
when i configure for glibc_headers is:

...
checking build system type... i686-pc-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
configure: running configure fragment for add-on linuxthreads
linuxthreads disabled because nptl add-on is also in use
configure: running configure fragment for add-on nptl
...

  why is the configure step first configuring for the linuxthreads
add-on, only to realize that it needs to turn it off immediately to
not clash with NPTL?

  i would have thought that setting GLIBC_ADDON_OPTIONS would have
been sufficient to take linuxthreads out of the picture entirely.
i'll admit it doesn't hurt, but isn't there a way to have the
configure avoid anything to do with linuxthreads?  have i missed
something obvious?
