kill-bb: Add it for killing abnormal bitbake processesrbt/kill-bb
There might be processes left after Ctr-C, e.g.: $ rm -f tmp/cache/default-glibc/qemux86/x86_64/ $ bitbake -p Press 'Ctrl-C' multiple times during parsing, then bitbake processes may not exit, and the worse is that we can't start bitbake again, we can't always reproduce this, but sometime. We can only use "ps ux" to find the processes and kill them one by one. This tool can kill all of them easily. Signed-off-by: Robert Yang <liezhi.yang@windriver.com>
