This is implemented in 4.3 and later.
I tried this - and it does not work here. I even added STAGE1_CFLAGS="-m32 -g" as suggested in an earlier comment. The build of gcc-4.3.2 bails out at this point: gmake[7]: Leaving directory `/var/vob/relman/admin/vob/devenv/Gcc/linux40_64/gcc-4.3.2/gcc' mkdir -p -- i686-pc-linux-gnu/libgcc Checking multilib configuration for libgcc...

I think that in gcc-4.3.2/Makefile the HOST_EXPORTS macro does not contain the appropriate CFLAGS. Or is this perhaps fixed in gcc-4.3.3? -- marek dot rouchal at infineon dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Known to fail| |4.3.2 Resolution|FIXED | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22073
