RFC: Register Build-Profile for ROCm and CUDA?

[Christian Kastner <ckk@debian.org>]

Hi,

the HIP flavor build of ggml takes a long time, which makes iterating on
package development cumbersome, especially since the things I'm working
on are entirely unrelated to HIP.

I added a package-local build profile [1] so that this can be skipped
easily.

However, I think it would make more sense to register an official build
profile for this [2], something like 'norocm', so that this same pattern
can be applied globally to other packages as well.

Theoretically 'nocuda' should also be registered, but CUDA-dependent
packages have their own special builds anyway so I'm not sure much would
be gained.

Thoughts? Objections?

Best,
Christian
