Re: porting OOT to gr3.8 Make failure

I don't exactly know why, but liborc-0.4.so gets linked into even the
simplest of OOT modules. Here's an example:

    linux-vdso.so.1 (0xbef7b000)
    libgnuradio-runtime.so.3.8.1 =>
/opt/gnuradio-3.7.12git/lib/libgnuradio-runtime.so.3.8.1 (0xb6eb0000)
    libgnuradio-pmt.so.3.8.1 =>
/opt/gnuradio-3.7.12git/lib/libgnuradio-pmt.so.3.8.1 (0xb6e61000)
    libboost_system.so.1.65.1 =>
/usr/lib/arm-linux-gnueabihf/libboost_system.so.1.65.1 (0xb6e35000)
    libstdc++.so.6 => /usr/lib/arm-linux-gnueabihf/libstdc++.so.6
(0xb6d22000)
    libgcc_s.so.1 => /lib/arm-linux-gnueabihf/libgcc_s.so.1 (0xb6cf9000)
    libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0xb6c01000)
    /lib/ld-linux-armhf.so.3 (0xb6f83000)
    libvolk.so.2.2.1 => /opt/gnuradio-3.7.12git/lib/libvolk.so.2.2.1
(0xb6b45000)
    libboost_program_options.so.1.65.1 =>
/usr/lib/arm-linux-gnueabihf/libboost_program_options.so.1.65.1 (0xb6ade000)
    libboost_filesystem.so.1.65.1 =>
/usr/lib/arm-linux-gnueabihf/libboost_filesystem.so.1.65.1 (0xb6abc000)
    libboost_thread.so.1.65.1 =>
/usr/lib/arm-linux-gnueabihf/libboost_thread.so.1.65.1 (0xb6a8f000)
    librt.so.1 => /lib/arm-linux-gnueabihf/librt.so.1 (0xb6a79000)
    libpthread.so.0 => /lib/arm-linux-gnueabihf/libpthread.so.0
(0xb6a54000)
    liblog4cpp.so.5 => /usr/lib/arm-linux-gnueabihf/liblog4cpp.so.5
(0xb6a1e000)
    libgmp.so.10 => /usr/lib/arm-linux-gnueabihf/libgmp.so.10 (0xb69c6000)
    libm.so.6 => /lib/arm-linux-gnueabihf/libm.so.6 (0xb6945000)
    liborc-0.4.so.0 => /usr/lib/arm-linux-gnueabihf/liborc-0.4.so.0
(0xb68e7000)
