jextract woes

[Maurizio Cimadamore]

I noticed that problem too - I was trying to use jextract on opencl 
headers too to take a look at what came out and found that issue.

This is something we fixed in the old jextract by having it include some 
clang headers by default - Sundar, I think this change is missing from 
current foreign-jextract?

For now you can workaround like this (at least, this is what I used):

jextract --filter cl.h -I 
/opt/clang/clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04/lib/clang/9.0.0/include/ 
/usr/include/CL/cl.h

This gave me something that was enough to Panama-ize some basic OpenCL 
examples I found on the web.

(The clang path you see is the one you use to build the Panama JDK)
