[Bug bootstrap/22073] New: build a 32bit gcc-3.4.4 on AMD64/Opteron Linux

["marek dot rouchal at infineon dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I would like to build a gcc/3.4.4 installation on RedHat Enterprise Linux 3.0 
(AMD64 - Opteron hardware), in which the gcc binaries are 32bit, such that this 
gcc installation would also be usable on 32bit (x86) hardware.
I tried all sorts of BOOT_CFLAGS=-m32 and/or CFLAGS_FOR_TARGET=-m32, 
unfortunately to no avail, as the default of "make bootstrap" is to build 64bit 
binaries on x86_64-unknown-linux-gnu.
The actual problem seems to be libiberty, which does not "see" the -m32 option 
when building the  stage1 compiler.
I hope this is not a FAQ - I did not find anything so far. And I am not saying 
this is necessarily a bug, maybe I just did not find the correct set of macros.

Thanks,

Marek
