+# This test would fail under Guix since gcc always adds RUNPATH entries,
+# so `$oldRPath` below for the built `no-rpath` binary is never empty.
+#
+# Hopefully the `no-rpath-prebuild.sh` test does include a binary
+# for this architecture without a RUNPATH, and this test is redundant,
+# so just skip it (see "Scripts-based Testsuites" in Automake's manual).
