+Remove useless check at build time
+
+At build time, Qwt looks whether the Qwt libraries are already
+installed in the destination directory, to avoid confusion between
+libraries installed system-wide and locally-built shared
+libraries. However, this behaviour conflicts with how Buildroot builds
+and installs libraries, so get rid of it.
