Comment(by howarth@…):

 The first thing I would try is start passing the correct triplets to
 configure. In my gcc4x packages on fink, I always passed...

  darwinvers=`uname -r|cut -f1 -d.`
  if [ "%m" = "powerpc" ]; then
   ../gcc-%v/configure %c --build=%m-apple-darwin${darwinvers} --host=%m
 -apple-darwin${darwinvers} --target=%m-apple-darwin${darwinvers}
  elif [ "%m" = "i386" ]; then
   ../gcc-%v/configure %c --with-arch=nocona --with-tune=generic
 --build=i686-apple-darwin${darwinvers} --host=i686-apple-
 darwin${darwinvers} --target=i686-apple-darwin${darwinvers}
  elif [ "%m" = "x86_64" ]; then
   ../gcc-%v/configure %c --build=x86_64-apple-darwin${darwinvers}
 --host=x86_64-apple-darwin${darwinvers} --target=x86_64-apple-
 darwin${darwinvers}
  fi

 I would suspect the build system is getting really confused cause
 config.log shows it thinks its building a 32-bit compiler....

 checking build system type... i386-apple-darwin10.0.0
 checking host system type... i386-apple-darwin10.0.0
 checking target system type... i386-apple-darwin10.0.0

 but you are forcing 64-bit code generation in the CFLAGS, CXXFLAGS and
 FFLAGS. If you read....

 and comment 28 from....

 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41180#c28

 You will see this approach is wrong.
