Hmmm. Nice to see the glibc folks suggesting crosstool-NG. :-)

Yes, this is the proper 'fix'. The default processor for ix86 is i386, which
lacks required instructions to implement NPTL. So, NPTJ requires at least a
i486. If your processor is a i686, then your fix is correct; if it is "only"
a i586 or a i486, then you'll have to use the proper setting, though.
