hi Yann,

this is entirely on purpose.  we don't use libgcc built out of the
toolchain tree as it has a chicken/egg problem with shared libraries
and configure.  the netbsd toolchain does not include any parts that
are shipped -- it merely builds it.

you may want to look at src/tools/gcc/README.mknative and look at
the bootstrap libgcc parts.

feel free to ask more questions -- mknative is difficut to get
bootstrapped (worse than it was, for sure.)
