libexecinfo-dev was removed in Alpine 3.17+, causing build failures. Add a configure check for execinfo.h and guard the include and backtrace() calls behind HAVE_EXECINFO_H. Also add Alpine CI matrix (3.17–3.21 + latest) to verify the build and --version on every PR. Closes redis#358 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Note
Low Risk
Low risk: build/CI portability changes only; runtime behavior changes only in crash-reporting paths where stack traces may now be omitted with a fallback message if
execinfo.his unavailable.Overview
Fixes Alpine (3.17+) build failures by making
execinfo.hoptional:configure.acnow probes for it andmemtier_benchmark.cppconditionally compiles theexecinfoinclude andbacktrace()/backtrace_symbols()usage with a graceful fallback message.CI is extended with a new
build-alpinematrix job that builds and runs./memtier_benchmark --versionacross multiple Alpine versions (3.17-3.21andlatest).Written by Cursor Bugbot for commit 5a871da. This will update automatically on new commits. Configure here.
