FWIW, we don't automatically look for clang yet, but with this it's 
possible to use plain clang with something like ./configure 
CROSSCC=clang. Such clang needs also a bunch of llvm tools (most notably 
lld) and some form of cross compiled libgcc or compiler-rt. I use clang 
from llvm-mingw, so it's something like ./configure CROSSCC=clang 
CROSSLDFLAGS=-rtlib=compiler-rt for me. This is an alternative, but if 
you have llvm-mingw wrappers installed, regular configure will find and 
use it just like it does now.
