+Upstream-Status: Backport
+
+On many architectures this test fails because binaries/libs produced by
+binutils don't pass elflint. However elfutils shouldn't FTBFS because of this.
+
+So we run the tests on all archs to see what breaks, but if it breaks we ignore
+the result (exitcode 77 means: this test was skipped).
