No, that's what's going to get the Makefile in the right order. If you run
it manually, you won't change anything.

What's the answer is trying to say is that llvm-config is getting -ldl in
the wrong order, so the line that generates the LDFLAGS should call
llvm-config twice (in that order), instead of once, as it's probably doing
it now.

To make sure this is, indeed, a solution, I recommend you to look into the
Makefile/Ninja rules, to see what is the generated order of libraries, and
if -ldl appears before or after LLVMSupport. If you change the Make/Ninja
file and it works, means the call to llvm-config is bad, and this needs to
be fixed in llvm-config itself, at least for the Android case.
