Subject: [PATCH 2/2] perf test: Skip test_arm_callgraph_fp.sh if unwinding isn't built in
Date: Tue, 23 Jan 2024 16:39:02 +0000

Even though this is a frame pointer unwind test, it's testing that a
frame pointer stack can be augmented correctly with a partial
Dwarf unwind. So add a feature check so that this test skips instead of
fails if Dwarf unwinding isn't present.
