LLVM IR is very target dependent. The IR knows about things like 
endian-ness, alignment, etc.

I'm currently building newlib for several LLVM targets and I create 
separate bitcode for each target. Each module has the target triple and 
target data string specific to the target.

Unfortunately you need an llvm-gcc for the target you want to support. M 
I think clang can generate code for multiple targets. Maybe you should 
try that.
