It's required for NPTL, I think, but it only comes into
play when building binaries, not libraries.  My current
patch (the one I pointed to earlier in the thread)
solves this by letting crosstool avoid building
binaries when building the bootstrap glibc.
It then goes back and builds binaries after everything
else is built.
This makes the linuxthreads build look more like the nptl
build without any nasty tricks and without much extra work,
I think.
