[Build] redefinition of ‘lua_likwid_rocmSupported’ with ROCM_INTERFACE=true

[okkevaneck]

Which version do you want to build? v5.3.0 - latest: https://github.com/RRZE-HPC/likwid/releases/tag/v5.3.0 Tarball: https://github.com/RRZE-HPC/likwid/archive/refs/tags/v5.3.0.tar.gz

Which architecture do you want to build for?

• [x] x86_64
• [ ] ARMv8
• [ ] POWER9
• [ ] Nvidia GPUs
• [ ] x86 (32 bit)
• [ ] ARMv7
• [ ] POWER8

To Reproduce

• Changes to config.mk (you may leave out PREFIX changes)
  • set ROCM_INTERFACE to true
• Changes to build configurations make/include_<COMPILER>.mk
  • N/A
• Any other changes
  • export ROCM_HOME variable: export ROCM_HOME=/opt/rocm
    • As a NOTE: we're building on a supercomputer with the Cray environment. Loading the rocm module does not set the ROCM_HOME variable which is required for config.mk.

I think it's as simple as moving the second function definition inside the else instead of outside. So I made a PR for you, but please correct me if I'm wrong! PR: #597

I think I fixed it already in the master branch but I'm not sure.
