Subject: [PATCH] tools/bashreadline: fix probe for dynamically linked readline
Upstream-status: sent to https://github.com/bpftrace/bpftrace/pull/3564/
Fixes: bsc#1232536

When bash links against libreadline dynamically, the probe fails as the
readline symbol is undefined until runtime. Fix this issue by adding a
fallback probe that hooks directly into libreadline.
