This seems problematic to me for a few reasons:

1. There is no 32-bit toolchains or libraries for little endian Linux systems
2. There is no support in the ELFv2 ABI for 32-bit object mode and there may be a number of places we assume that little endian systems use ELFv2 ABI
3. There are a number of places that make the assumption that little endian systems must be 64-bit so there's no checking for 32-bit mode (which will likely result in 64-bit specific code gen)

Since this seems to be for a very specific use case, can we perhaps severely restrict the support for 32-bit little endian mode (perhaps BSD only, no Altivec/VSX, etc.)?
