Hm.. so the C backend works differently if I configure LLVM to be a cross
compiler? I am using a cross-compile toolchain as a backend (feeding it the
"llc
-march c" output), so I'm a bit confused. I'm not looking for a
target
independent IR, either...

Regarding building LLVM as a cross compiler, I assume it should be pretty much
identical to building gcc as a cross compiler? (sans adding the LLVM_OBJ
directory when configuring).

Yes, it generates output matching the target triple stored in the .bc 
file.

Yep
