So ghc-stage1 is working. Good! Now just to find why your base is broken,
please rebuild ghc completely and this time does not use any -j 5 option. It'll use just one core, but will stop on the first error. Let's see how far you get.
Ah. Alright, it took a while longer.

This is weird, I think I'm not even using LLVM.
This is not weird at all! GHC does not provide ARM NCG and so it is using LLVM if you compile ARM registerised build.
But "./configure [...] --enable-unregisterised" should mean using the C backend, not LLVM, right? So this still looks strange. Also there is an explicit "-fllvm" on the failing ghc-stage1 command line. What is in your build.mk? Maybe you are using one of the build flavors that sets -fllvm explicitly? That said you can also try installing the supported version of LLVM for ghc 7.10, which is LLVM 3.5. Regards, Reid Barton
