Remove autoconf, bison, texinfo, gcc, g++, and jq from apt-get install
since they are preinstalled on the ubuntu-24.04 runner image.
Replace the OSTYPE case block in run-gnu-test.sh with command -v probing
for MAKE, NPROC, and READLINK, as suggested by @oech3.
- Add extraction of GNU test results into JSON artifacts
- Add aggregation job to summarize results and compare against reference
- Enable continue-on-error for GNU tests to allow workflow completion on failures
- Align log compression and upload behavior with coreutils CI
This checks out GNU tar and runs its test suite
against our built tar binary.
The hooks in autotest aren't working correctly,
so we manually overwrite the built binary with
our generated binary for testing.
