I think there's a bug report about this. Sycl (iirc) introduced a change that caught invalid things with types that were previously ignored. @jdoerfert is on point I think.

`-DLLVM_ENABLE_PROJECTS="clang;compiler-rt;libcxxabi;libcxx;libunwind;openmp" `
^ That works, if the compiler in question can build things like an nvptx devicertl, which essentially means if it's a (sometimes very) recent clang. A generally easier path is
as that will build clang first, then use that clang to build openmp.

Won't help in this particular instance - if I understand correctly, it's a misfire from using glibc headers on the nvptx subsystem - though that stdlib.h looks like it shipped as part of libc++.
