Building from svn on amd64

[Henning Hasemann]

Im trying to build the current svn version of gdc on an amd64 machine
on top of the gcc-4.1.2-core sources. The setup-script complained that
it cant patch some tree-thingies but I assumed that this would only
affect treelang and carried on.

configure runs fine, but make stops with error messages like this:
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: File not found
(translated from german error message)

One of the failed gcc calls is here:
/home/henning/src/gcc-4.1.2/host-x86_64-unknown-linux-gnu/gcc/xgcc
-B/home/henning/src/gcc-4.1.2/host-x86_64-unknown-linux-gnu/gcc/
-B/usr/local/x86_64-unknown-linux-gnu/bin/
-B/usr/local/x86_64-unknown-linux-gnu/lib/
-isystem /usr/local/x86_64-unknown-linux-gnu/include
-isystem /usr/local/x86_64-unknown-linux-gnu/sys-include -O2 -O2 -g
-O2   -DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes

-I32 -I../.././gcc -I../.././gcc/32 -I../.././gcc/../include
-I../.././gcc/../libcpp/include  -m32 -g0 -finhibit-size-directive
-fno-inline-functions -fno-exceptions -fno-zero-initialized-in-bss

-fno-asynchronous-unwind-tables -fPIC \ -c ../.././gcc/crtstuff.c
-DCRT_BEGIN -DCRTSTUFFS_O \ -o 32/crtbeginS.o

Im a little surprised to see a "-m32" in there, any hints?
