seawasp, which runs some bleeding-edge version of clang, has been falling
over for the last couple of weeks:

/home/fabien/clgtk/bin/clang -Wno-ignored-attributes -fno-strict-aliasing -fwrapv -O2 -D__STDC_LIMIT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_CONSTANT_MACROS -D_DEBUG -D_GNU_SOURCE -I/home/fabien/clgtk/include -I../../../../src/include -D_GNU_SOURCE -I/usr/include/libxml2 -flto=thin -emit-llvm -c -o llvmjit_types.bc llvmjit_types.c
llvmjit.c:21:10: fatal error: 'llvm-c/OrcBindings.h' file not found
#include <llvm-c/OrcBindings.h>
^~~~~~~~~~~~~~~~~~~~~~

I suppose this is related to what you are talking about here.
If so, could we prioritize getting that committed? It's annoying
to have the buildfarm failures page so full of this one issue.
