Cannot compile gcc-4.4.1 on Mac Pro---libiberty.a file is not of required architecture---Please Help

[Jeremy Conlin]

I have been trying to compile gcc-4.4.1 on my Mac Pro with 64bit Xeon
processor with no success.  I have the following variables set

CFLAGS='-m64'
CXXFLAGS='-m64'

and I have run ./configure without any command-line options.  When I
run make, everything runs smoothly for awhile then I get the error
copied below.  Can someone help me identify what is wrong?
Thanks,
Jeremy
