Did you build llvm by simply using configure - make make install entered
manually, rather than mk-dist?
I had similar troubles as you (Visual C++ interference and "llvm-config not
found") while running a native MXE build.
MXE configure has an option "--enable-jit" but the output from
'octave_config_info' from a cross build shows it just didn't work.
I think src/octave.mk has to be patched to (attempt to) build llvm support
(i.e., add the --enable-jit flag to the configure options there). I was
going to try that tonight (with an older MXE checkout) but I have little
hope -it didn't work last time I tried.
