Recipe updates for non-amd64 architectures

[aandvalenzuela]

This PR includes aarch64 and pcc64le archs in the recipes. I have kept compiler definition for amd64, but it needs to be modified for testing to the corresponding compiler. Aside, this PR also removes padding in the installation path.

@aandvalenzuela could you please check if packages in backports are already in 0.19?

[aandvalenzuela]

@iarspider is there any reason why branch CMSSW_12_6_X does not share the git history with branch CMSSW_12_5_pre4?

[iarspider]

I wanted to keep history clean

They are not, I'd say: https://github.com/iarspider/cms-spack-repo/tree/CMSSW_13_0_X/repos/backports/packages Backported packages are:

• benchmark (upstream: https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/benchmark/package.py),
• igprof (https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/igprof/package.py),
• professor (https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/professor/package.py),
• rapidjson(https://github.com/spack/spack/blob/develop/var/spack/repos/builtin/packages/rapidjson/package.py).

Many thanks @iarspider!

Can you try porting this to 13_0_X branch? I want to setup an IB using that branch before X-mas

[aandvalenzuela]

Yes, I will try. I think it can take some time due to uncommon histories. CMSSW_13_0_X doesn't build for me, is it for you?

[iarspider]

Everything except cmssw should build

[iarspider]

cmssw is outdated, you can add any recent (e.g. today's) tag in there. Just keep the placeholder line.

You can try getting this PR as a diff, then figure out any patch conflicts you get.
