Thank you, seeing that message was very helpful.

binutils-2.17 is fine. So, I downloaded that and tried again, and got  
MUCH farther, but still ran into some errors:

gcc -g -O2   -c -o flat_bl.o ../../combined/gprof/flat_bl.m
../../combined/gprof/flat_bl.m:2: error: syntax error before ‘%’ token
make[4]: *** [flat_bl.o] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-gprof] Error 2
make: *** [all] Error 2


I'm not sure what a .m file is. For Mac OS X, .m is an Objective-C  
file. However, this file does not look like Objective-C to me. Not  
sure what it's supposed to be. There is a .c file with the same name  
in the same dir.

I ran configure with:

$ ../combined/configure --prefix=/usr/local/xscale-gcc-test -- 
target=xscale-elf --enable-languages=c,c++ --disable-nls --with-newlib

My tools' versions (Mac OS X's Xcode 3.0):

$ gcc -v
