Hi
working on creating a fate test.
I am stumbling on probably a dumb issue; I want to re-use a file already
used for mapchan test:

FATE_MAPCHAN-\$(CONFIG_CHANNELMAP_FILTER) += fate-mapchan-6ch-extract-2
fate-mapchan-6ch-extract-2: tests/data/asynth-22050-6.wav
(first two lines in ffmpeg.mak)

But I can't get a hold of this file. I have no data folder from git;
after running a fate test, I get a fate-suite folder but this file is
not included.

Thanks for any hint.
