If you configure to build a 32-bit compiler on a 64-bit Linux system with:
CC='gcc -m32' /src/trunk/configure --{target,host,build}=i686-pc-linux-gnu ...
the compiler fails because it defaults to 32-bit code but the standard
assembler is 64 bit, and it fails in building libgcc. If you are building in
such an environment, the compiler should be modified to pass --32 to the
assembler.
Note, there is the work around of putting a 32-bit assembler in the --prefix
directory so that it builds correctly, but it would be nice to have it fixed.
