+Subject: [PATCH] Provide SONNET_NO_BACKENDS option to deactivate build
+ failures with no backends
+
+For cross-compilation tooling, both a native host and a target device
+build is needed in which the first provides the parsediagrams6
+executable. We do not want to build any plugins when just the
+cross-build tooling is being built.
