-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.
