--- Comment #7 from Alan Modra <amodra at gmail dot com> --- On x86_64-linux you can run 32-bit binaries. On powerpc64le-linux you can't. It's that simple. -m32 support in powerpc64le gcc, by default, doesn't make sense until we have - supported and tested compat layer in the kernel - supported and tested gcc, binutils and glibc We might even want to change the 32-bit ABI for powerpcle. The change I made wasn't "just to be able to omit" --disable-multilib. It was also to fix the wrong default of enabling -m32 support in powerpc64le gcc. Another data point: llvm doesn't support -m32
