perf tools: Add -lutil in python lib list for broken python-config
On some system the perf-config is broken, causes link failure like this:
/usr/lib64/python2.7/config/libpython2.7.a(posixmodule.o): In function `posix_forkpty':
/opt/wangnan/yocto-build/tmp-eglibc/work/x86_64-oe-linux/python/2.7.3-r0.3.1/Python-2.7.3/./Modules/posixmodule.c:3816: undefined reference to `forkpty'
/usr/lib64/python2.7/config/libpython2.7.a(posixmodule.o): In function `posix_openpty':
/opt/wangnan/yocto-build/tmp-eglibc/work/x86_64-oe-linux/python/2.7.3-r0.3.1/Python-2.7.3/./Modules/posixmodule.c:3756: undefined reference to `openpty'
collect2: error: ld returned 1 exit status
make[1]: *** [/home/wangnan/kernel-hydrogen/tools/perf/out/perf] Error 1
make: *** [all] Error 2
$ python-config --libs
-lpthread -ldl -lpthread -lutil -lm -lpython2.7
In this case a '-lutil' should be appended to -lpython2.7.
(I know we have --start-group and --end-group. I can see them in command
line of collect2 by strace. However it doesn't work. Seems I have a
broken environment?)
