Fedora compilation instructions are incorrect

[FSilveiraa]

I tried the setup on a completely new system with Fedora 40, following the instructions, and I noticed some of them were wrong:

• Besides rocblas-devel and hipblas-devel you also need the rocm-hip-devel package, otherwise you'll get an error about 2 missing header files: hip/hip_fp16.h and hip/hip_runtime.h
• I did not have to link anything on /opt, all libraries were found with no issue, but it was looking for the amdgpu-arch which in Fedora is amdgpu-arch-17. I fixed this by symlinking /usr/bin/amdgpu-arch-17 to ~/.local/bin/amdgpu-arch

That last issue only happens if you don't specify the GPU architecture, which you have to like the guide specifies, otherwise you'll get a runtime error after loading the model into memory. I can open a PR for the README, but I'd like someone else to confirm this if possible.

Ran into this when trying to debug building under Fedora 41.
Can confirm the above is correct, and creating /opt/rocm actually causes issues in finding hipconfig and should therefore be avoided.
