The build of file libperf-jvmti.so succeeds but the resulting
object fails to load:
# ~/linux/tools/perf/perf record -k mono -- java \

hog 100000 123450
Error occurred during initialization of VM
Could not find agent library /root/linux/tools/perf/libperf-jvmti.so
in absolute path, with error:
/root/linux/tools/perf/libperf-jvmti.so: undefined symbol: _ctype
Add the missing _ctype symbol into the build script.
