I have a 64-bit GNU/Linux system (x86-64 or s390x) and want to build GCC
with -m32 or -m31 support in the compiler.  However, I do not have glibc
for i386 or s390 installed, only the native (64-bit) version.  This
means that I need to build with --disable-multilib.

Is there still a way to get -m32 or -m31 support in the compiler, for
compiling and linking with -nostdlib?


Does --enable-targets=all help?


Right, that seems to work.  Thanks!

Florian
