Commit Message

Pratik Farkase Oct. 29, 2026, 1:11 p.m. UTC 
Build and run the lttng-ust unit test suite under ptest, modelled on the
liburcu ptest support: the run-ptest script executes each TAP test from
the tests/unit subdirectories and reports PASS/FAIL. The compile tests,
benchmarks and the abi0-conflict regression test (unstable under QEMU)
are excluded.

The ust-elf test ships prebuilt, intentionally foreign-architecture ELF
fixtures, so they are kept from being stripped and the related QA checks
are relaxed for the ptest package.

Tested on qemuriscv64 with ptest-runner.
