+When cross compiling a target gcc, target flags may be used on the host
+
+Configure identifies a number of warning flags (WARN_CFLAGS and
+WARN_CXXFLAGS) from the $CC value. The cross compiler may be different
+from the host compiler and may not support the same set of flags. This
+leads to problems such as:
+
+cc1plus: error: unrecognized command line option "-Wno-narrowing"
+cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
+
+Work around this problem by removing the warning flags from the
+BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.
