Subject[PATCH 30/30] perf tools: Disable test code
Date
NOTE: hack

Forcing test objects not to be compiled into perf code.
This saves almost 1MB of perf binary size on my setup:

# standard perf binary
$ ls -l perf
-rwxrwxr-x 1 jolsa jolsa 10283684 Jan 1 15:52 perf

# current perf binary
$ ls -l perf
-rwxrwxr-x 1 jolsa jolsa 9303174 Jan 1 15:58 perf
