suggested updates to Makefile and documentation on how to compile the software

[bcrowell]

To get this to compile on ubuntu, I had to edit the Makefile to remove the two references to lv2core.

In the docs, it might be helpful to note that the following ubuntu packages suffice: lv2-c++-tools fftw3 libfftw3-dev lv2-dev lv2proc

Off-topic, but I compiled it using following:

clear
cd $HOME/Desktop

sudo apt-get -y install curl g++ gcc git libfftw3-3 libfftw3-dev lv2-c++-tools make mingw-w64
sudo wget https://raw.githubusercontent.com/lv2/lv2/master/lv2.pc.in -O /usr/lib/pkgconfig/lv2core.pc

git clone https://github.com/x42/lv2vst
git clone https://github.com/jeremysalwen/kn0ck0ut-LV2

cd kn0ck0ut-LV2
make
make install
