Automated testing of GNU Radio builds
summary
Uses Buildbot + OpenEmbedded to assemble full GNU Radio images, package QA scripts into deployable test bundles, and boot them under emulated 32/64-bit ARM and x86 (QEMU) to run ctest-based QA over real binaries. Finds concrete failures (gcc-9 on zeus miscompiles an FFTW function), copes with flaky tests and noisy timing output by post-filtering, and commits test-run logs into a repo so diffs reveal regressions; test invocation uses SSH scripts that are brittle but generally reliable. git-tracked test results
