KemoNine a2ddfb0ee9 Fix Plume arm builds (#427)
llvm latest svn commit is broken as of 2019/01/12. This patch pins the llvm+lld versions used for arm compiles.

It also tweaks the architecture detection to be more reliable in multi-lib/multi-arch situations where the CPU is 64bit but the runtime is 32bit.
