[FFmpeg-devel] [PATCH v3] fate: Add a target for listing failed tests

[Martin Storsjö]

If running tests with "make -j<N> fate", the execution will stop
after the first failing test. To get an overview of the whole
test suite, one rather would run "make -k -j<N> fate", which then
again buries the results about what tests actually failed further
up in the console log.

Add a target so one can run "make fate-list-failing", to see a list
of all tests that failed the last time they were executed.

Also add a companion target "fate-clear-results" which removes all
the old test results. (When executing a subset of tests, the result
files of all tests that aren't executed stay untouched. This also
allows getting rid of results for tests that no longer are present
in the testsuite.)

v3: Renamed the clear target to "fate-clear-reports", and updated
the docs accordingly. Added the check for whether there are any
*.rep files at all.
