The receipt is simple, first try LLVM-based build on fast x86 machine 
(i.e. cd mk; cp; edit to uncomment BuildFlavour 
= quick-llvm) and once it's working attempt LLVM-based (the only way) 
build on ARM.

Also, forget unregisterised build, rather ask Austin how is it looking 
with his work on fixing LLVM codegen in HEAD.

And a last note: please keep in mind that cross-compiling is supported 
only using NCG. LLVM is completely out of question now, so you will have 
some work here anyway. I don't think it'll be complicated, but certainly 
some hacking with passing target triplet down to LLVM, but IIRC you've 
already found that anyway...
