undefined symbols generated

I'm on ridiculous idea
there's a closed source shippped binary [here](https://github.com/antoineco/broadcom-wl)
I want to recompile it for armhf
but there's some symbols on IR that were not in the original binary
something like `global_var_42e488`

so modpost fails

Start by reproducing the armhf recompilation from the linked broadcom-wl binary and inspect the generated IR for symbols such as global_var_42e488. Compare those symbols with the original binary and determine what causes modpost to fail; done means the generated output no longer produces unexplained undefined symbols.
