# Regression guard for #8342: libstinkytofu must never carry a DT_NEEDED on a
# plugin. A plugin is discovered and dlopen'd by the host at runtime, so linking
# one into libstinkytofu would invert the relationship — and if that plugin were
# absent (e.g. STINKYTOFU_BUILD_EXAMPLES=OFF) the loader would fail to load
# libstinkytofu itself, surfacing as "libstinkytofu not found".
#
# Invoked as a CTest with -DLIB=<path to libstinkytofu> -DREADELF=<readelf>.
