This PR adds the build script for the triton package on ppc64le. The build was verified in a bare UBI10 container image. This build script builds LLVM entirely from source as a part of the build script as this is needed for building triton on Power. Please let me know if any changes are required to the build script.

Please add build-info.json file. Refer to template - and example .

As of now, the team is working on enabling UBI10 in CI. Therefore, this PR will need to wait until UBI10 support has been added to the CI pipeline.

@cdeepali I have added build_info.json. Let me know if any changes are needed. Thanks.

Thanks @Daniel-Schenker. Please update the PR as per the suggestions in #8473 (comment).
Please also rebase PR with master to pull the changes in the wrapper script that enable build on UBI10.

@cdeepali Changes addressed

[cdeepali]

I should have mentioned earlier, that the build-info.json also requires a block like:

 "*": {
    "build_script": "z3-solver_4.15.4_ubi_10.sh"
   }

as in https://github.com/ppc64le/build-scripts/pull/8486/changes.
