+By default, the boost test option is mandatory for build environment
+detection. 
+This patch suppress this dependency and allows the test part only if
+build_test is enabled at the Buildroot level.

+	  GNU Radio is a free & open-source software development
+	  toolkit that provides signal processing blocks to implement
+	  software radios. It can be used with readily-available
+	  low-cost external RF hardware to create software-defined
+	  radios, or without hardware in a simulation-like
+	  environment. It is widely used in hobbyist, academic and
+	  commercial environments to support both wireless
+	  communications research and real-world radio systems.
