Subject: turris: use force-make machinery to not need to debug on server

This is now configured so that if build of package fails it runs
compilation again with logs printed.

+This is make wrapper that tries to run build really hard. It runs build multiple
+times while it decreases paralelism. You can set amount of retries done given
+number of parallel jobs. You can also specify speed how fast number of parallel
+jobs are going to decay using -d option. There is last additional run on top of it
+all that appends all arguments to make call passed to -f option.
+
+Options:
+  -j NUM   Number of parallel jobs, modified and passed to make (in default 1)
+  -d OP    Divider used to decrease number of parallel jobs (in default 2)
+  -c NUM   Number of retries before paralelism is decreased (in default set to 1)
+  -f ARGS  Additional argument to be used for last single job attempt (can be
+           passed multiple times)
