[FFmpeg-devel] [PATCH] allow overriding SAMPLES with environment variable

[Reimar Döffinger]

Hello,
it would be enough to just have it apply if --samples was not passed to
configure, but I didn't know a good way to do that.
Currently, you can't just set a SAMPLES environment variable and
the fate tests will use it, you have to either specify the path
to configure or specify it on the command-line.
Both seem a bit inconvenient to me, so I did the following change:
