This fixes cross-building perf for arm64 on Ubuntu, as well as native.
Before this patch this error:

  LINK     libperf-jvmti.so
/usr/lib/gcc-cross/aarch64-linux-gnu/6/../../../../aarch64-linux-gnu/bin/ld: cannot find -lelf
collect2: error: ld returned 1 exit status

was avoided with make NO_JVMTI=1.

So for this and the rest of the series, FWIW:

Thanks,
