Undefined reference when building bindgen

Solved this issue.

First rule of thumb is to use distribution-supplied packages so that everything is compiled with the same compiler version and is compatible.

And the solution for the two missing symbols was to add "-lclangLex" to the LIBS line in clang/Makefile. This worked with both clang/llvm 6.0 and 7.0 installed on Debian from official Debian packages.

I also get these errors on Linux
