File praat-use_system_libs.patch of Package praat

From: Luigi Baldoni <aloisio@gmx.com>
Date: 2017-07-29 13:47:50 +0200
Subject: Use system libraries when possible

Praat includes a number of external libraries that then builds
internally.
Some (gsl, glpk and portaudio) can be replaced by system ones,
other like espeak and FLAC are too heavily patched for the program
to be compatible with upstream ones.
