pytorch: useflag rocm refers to invalid ebuild (dev-util/amd-rocm-meta)

[ekaats]

When compiling pytorch with the useflag 'rocm', there is an invalid reference to 'dev-util/amd-rocm-meta'. perhaps that should be rocm-opencl-runtime?

Oh, this branch (with rocm enabled) is long unseen and was configured against https://github.com/justxi/rocm/ repository, but recent versions of many of ebuilds there were merged to the mainline Gentoo repository, so it definitely needs revisiting. I actually plan to do it soon hopefully, but now it's probably broken. Will keep you updated here.

Maybe we won't need rocm anymore going forward since a lot of OpenCL stuff is being integrated into the open source Mesa library. So perhaps we don't need Rocm at all. In that case all that may need to be done is to check if 'media-libs/mesa' is build with the 'opencl' flag as well.

Haven't tested this yet, but I'll let you know when I do.
