Re: [crosstool-ng] error building x86 toolchain

Which reminds me something very similar a while back: the minimum suported

Seems to be this reference:

3) NPTL has not been ported to i386, only i486+, x86_64,
  ia64, ppc32, ppc64, s390, s390x, alpha, sh and sparcv9.
  i386 (and sparc < v9) lacks atomic instructions powerful
  enough for NPTL needs.  Well, I have tried to port NPTL
  to i386, http://sources.redhat.com/ml/libc-hacker/2004-05/msg00019.html,
  but that port is severely limited and maintaining two
  different IA32 ports would be too much work.
  So for NPTL by default we need a i486-*-linux build of
  glibc at least
