File distribution.changes of Package failed_distribution

Repair summary for failed_distribution

Root cause:
- The spec file had an invalid ExclusiveArch declaration. Original line contained malformed tokens ("%ix86 x86_64 %arm ..."), which would cause the rpm spec parser to fail.

Change applied (minimal):
- File modified: distribution.spec
- Original line (approx):
    ExclusiveArch:  %ix86 x86_64 %arm aarch64 ppc64 ppc64le s390x riscv64
- New line:
    ExclusiveArch:  %ix86_64 %arm aarch64 ppc64 ppc64le s390x riscv64

Notes:
- No source archive was extracted; only the spec file was edited in place.
- The rest of the spec file was left unchanged except for correcting the ExclusiveArch token.

Files changed:
- temp_workspace/failed_distribution/distribution.spec
- temp_workspace/failed_distribution/distribution.changes

Next steps:
- Uploading the repaired package directory to OBS for verification.
