New failure:
- [ ] `libclc-git` fails with llvm11

It used to build before the update. Now I see this error:
```
LLVM-CC amdgcn--amdhsa/lib/math/fmax.cl.bc
LLVM-CC amdgcn--amdhsa/lib/math/fmin.cl.bc
clang-11: error: cannot find ROCm device library. Provide its path via --rocm-path or --rocm-device-lib-path
, or pass -nogpulib to build without ROCm device library.

Updating to latest git revision [9aa6f350a6ce0f2cfc7e489495af8899ca74e079](https://github.com/llvm-mirror/libclc/commit/9aa6f350a6ce0f2cfc7e489495af8899ca74e079) of 2019-10-27 doesn't change this.
Not sure what to do here. It's blocking my try to do (yet) another bootstrap as `mesa` depends on it, and the chain back to `cairo`, `gobject-introspection`, `libsecret`, `git`, `dtc`, `qemu-user-static`, `libgpg-error`, `libgcrypt`, `libmicrohttpd`, `elfutils`, `gdb`, `atf`, `xbps`, `base-chroot` when trying to do a cross build for `base-chroot` for `i686`.
