Hello,
I am trying to compile Beignet on Yocto 3.0.1 (zeus) 32 bits for Intel
Coffee Lake with UHD 630 Graphics. I have the meta-clang layer
<https://github.com/kraj/meta-clang> which provides clang/llvm 9.0. My
compilation is failing. I have a bitbake recipe for beignet, with a script
borrowed from meta-beignet <https://github.com/rossburton/meta-beignet> and
edited (given below). Is there any patch for compiling beignet with LLVM
9.0 for 32 bits?
I am encountering the following issues during the configure step:
```

The following is my beignet recipe for Yocto:
```

do_install_append() {

${D}${bindir}/include
}
```
I would appreciate any help or pointer.
