Something must be seriously wrong then.
I just built a Yagarto (20110429) here. The only thing I needed in
addition to Michael's script was the attached patch, because newlib
fails to build all the crt* stuff for ARMv6-M.
Yagarto uses a slightly different approach: they build all the
additional prerequisites into their `addontools' directory.

Never trust an operating system you don't have sources for. ;-)
