+	bool "rt-tests"
+	help
+	  Set of utilities for testing the real-time behaviour of a
+	  Linux system.
+
+	  All tools are simple C programs with no dependencies, except
+	  the hwlatdetect utility, which is a Python script and
+	  therefore requires the Python interpreter. It will only be
+	  installed if a Python interpreter has been selected in the
+	  Buildroot configuration.

+Fix various minor issues with rt-tests build system
+
+The issues fixed are :
+
+ * Remove the automatic NUMA detection from the host
+   architecture. This is broken when doing cross-compilation. One can
+   still set NUMA=1 if NUMA support is desired.
+
+ * Expand the CFLAGS provided through the environment instead of
+   overriding it.
+
+ * Provide a HASPYTHON variable to tell whether the target system has
+   Python or not. Otherwise, the build system simply tests whether
+   Python is available on the host. The PYLIB variable is also changed
+   so that it can be overriden from the environment, in order to
+   provide the correct Python module location for the target.
