Pretty much looks the same.

Ok. It was in /usr/tmp/cross/build/gcc, which is where I'm trying to build 
from. The link relevant lines I could find are:

*link:
%{h*} %{v:-V}    %{b} %{Wl,*:%*}    %{static:-dn -Bstatic}    %{shared:-G -dy %{!mimpure-text:-z text}}    %{symbolic:-Bsymbolic -G -dy -z text}    %{G:-G}    %{YP,*}    %{R*}    %{compat-bsd:      %{!YP,*:%{p:-Y P,/usr/ucblib:/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib}        %{pg:-Y P,/usr/ucblib:/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib}        %{!p:%{!pg:-Y P,/usr/ucblib:/usr/ccs/lib:/usr/lib}}}      -R /usr/ucblib}    %{!compat-bsd:      %{!YP,*:%{p:-Y P,/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib}        %{pg:-Y P,/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib}        %{!p:%{!pg:-Y P,/usr/ccs/lib:/usr/lib}}}}    %{Qy:} %{!Qn:-Qy}

*linker:
collect2

*link_command:

 }}}}}}


The only file I seem to be able to find is the "collect2", which is a binary
in the gcc directory. Its a binary, so its not being too useful.

I'll be more than happy to take a look. I've been using the steps from
http://www.objsw.com/CrossGCC (Section 4), and that is how I've gotten myself
down this road.
