tools lib traceevent: Add plugin build support
Backporting missing pieces of plugin building infrastructure:
- Adding Makefile 'plugins' target to build all
defined plugins
- Adding Makefile 'install_plugins' target as 'install_lib'
target dependency
- Link plugin objects with shared object building
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
Plugins are by default installed into following locations:
'$(HOME)/.traceevent/plugins'
- If we are installing under $(HOME)
'$(prefix)/lib/traceevent/plugins'
- Otherwise
This path is propagated to the plugin object as a plugins search path.
