Yes, that's expected. The i386 processor (yes, I do speak about the i386!)
is missing some instructions (I think it was cmpx, aka CoMPare and eXchange)
that is need for proper NPTL behavior. So you can not build NPTL for the
i386. For NPTL, you need at least an i486.

So, if you really have an i386 and you need threads, you will have to use
the linuxthreads implementation (instead of NPTL). That means a glibc 2.5.

Are you _sure_ you have an i386? If not, you'll have to tell crosstool-NG
with:
  Target options  --->
    ()  Architecture level
    ()  Emit assembly for CPU
    ()  Tune for CPU
