Updated build instructions for portaudio MinGW builds on MS Windows

Browse Source 
These instructions  recommend building v19.06, and  patching to enable
shared library builds. This will allow  users to substitute a build of
libportaudio-2.dll  with   ASIO  support   if  required.    We  cannot
redistribute  binaries  with  proprietary, closed  sources,  like  the
Steinberg  ASIO  SDK,  although  users can  build  it  themselves  for
personal use.

Note that on Windows portaudio will only build static libraries using

as users may wish to substitute a build of the library with ASIO
support for personal use (we cannot redistribute binaries built from
proprietary closed source sources like the Steinberg ASIO SDK).
In order to build DLLs on Windows the configure script requires a
patch as follows:
sed -i -e 's/-luuid//g' ~/src/portaudio/configure
This removes linker dependencies on the MS uuid library since it is
only available as a static archive and using that would disallow
shared library creation.
