oprofile: update --with-kernel option to find perf_event.h
Update --with-kernel=${STAGING_DIR_HOST}/${prefix} to find kernel
headers (linux/*.h) to fix the error:
| checking kernel supports perf_events... unknown -- perf_event.h not found
| ERROR: You requested to build oprofile with '--with-kernel=/buildarea/lyang1/test_f2/tmp/work-shared/qemux86/kernel-source',
| but headers were not accessible at the given location.
| Be sure you have run the following command from within your kernel source tree:
| make headers_install INSTALL_HDR_PATH=<kernel-hdrs-install-dir>
| Then pass <kernel-hdrs-install-dir> to oprofile's '--with-kernel' configure option.
| configure: error: Unable to build oprofile. Exiting.
