Thomas Richter 6a6fac11b1 perf jvmti: Link against tools/lib/ctype.h to have weak strlcpy()
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.
