SV platform dependency builds

/** @file patest_wire.c

        @ingroup test_src

        @brief Pass input directly to output.

        Note that some HW devices, for example many ISA audio cards

        on PCs, do NOT support full duplex! For a PC, you normally need

        a PCI based audio card such as the SBLive.

        @author Phil Burk  http://www.softsynth.com

 While adapting to V19-API, I excluded configs with framesPerCallback=0

 because of an assert in file pa_common/pa_process.c. Pieter, Oct 9, 2003.
