The build of file libperf-jvmti.so succeeds but the resulting object fails to load:
# ~/linux/tools/perf/perf record -k mono -- java \ -XX:+PreserveFramePointer \ -agentpath:/root/linux/tools/perf/libperf-jvmti.so \ 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.
Fixes: c5d048240e49 ("perf jvmti: Link against tools/lib/string.h to have weak strlcpy()")
