Starting with version 0.0.1~20160212+git0c13e83-2, all binary files
have been renamed to $filename-perf suffix.

For example: execsnoop => execsnoop-perf

Similarly, the manpages have been renamed. This is done to accommodate
users who would like to use perf-tools-unstable, parallely with the
eBPF Compiler Collection Tools from the bpfcc package.

Both upstreams work closely on the projects, thus the common names.

FUNCTION_PROFILER is not defined in Debian's 3.16.0-4, so
/usr/bin/funccount can't be executed.
