Responding to myself: Same result without --with-float=soft; build stops
when nothing is found under subdirectories of powerpec-eabi/nof.
Hmm. I thought the nof-stuff was specifically related to emulation of
floats. Should it really try to build something from the nof-tree if
hardware floats are used?
A more elementary question: What is the current recommendation for building
a cross-compiler - use bootstrap-GCC to build newlib before building full
GCC, or one-pass build by linking the newlib sources under GCC sources? From
question 2 at http://sources.redhat.com/newlib/faq.html, I figured the
one-pass build is an appropriate method.
