Ah. Alright, it took a while longer.

 $ ./configure --target=arm-linux-gnueabihf --with-gcc=arm-linux-gnueabihf-gcc-sysroot --enable-unregisterised && make

You are using a new version of LLVM that hasn't been tested yet!
We will try though...
opt: /tmp/ghc23881_0/ghc_1.ll:7:6: error: unexpected type in metadata definition
!0 = metadata !{metadata !"top", i8* null}
     ^

make: *** [all] Error 2

This is weird, I think I'm not even using LLVM.

Before this, there were loads of things like these:
/tmp/ghc23862_0/ghc_2.hc:1528:30:
     warning: function called through a non-compatible type [enabled by default]
     ((void (*)(void *))(W_)&barf)((void *)(W_)&c7G_str);;
                                  ^

     note: if this code is reached, the program will abort
