For the most part I don't build these toolchains, so that's not an  
option.  Plus, I like having each toolchain fully contained in its own  
directory.  And this worked fine before pixman.

A few more options than that, but basically yes.

I can get past this particular obstacle by doing something like:

(PATH=/home/scott/.../powerpc-linux-gnu/bin:"$PATH" ./configure  
--cross-prefix=powerpc-linu-gnu- ...)
and then
(PATH=/home/scott/.../powerpc-linux-gnu/bin:"$PATH" make)

...but then I run into the problem that --extra-cflags and  
--extra-ldflags don't get passed into pixman.
