Fixing this problem, introduced recently:
$ perf test python
16: Try 'import perf' in python, checking link problems : FAILED!
In verbose mode we find out what is missing:
$ perf test -v python
16: Try 'import perf' in python, checking link problems :
--- start ---
test child forked, pid 24894
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /tmp/build/perf/python/perf.so: undefined symbol: find_next_bit
test child finished with -1
---- end ----
