    systemtap: fix native linking on recent Ubuntu
    
    The latest Ubuntu uses yet more aggressive hardening options, which causes the
    unconventional build order used by systemtap to fail.

+Subject: [PATCH] staprun: fix linking if monitor is enabled
+
+If the monitor is enabled, monitor.c needs to link against json-c and ncurses.
+Instead of adding these linker flags to AM_CFLAGS (global CC flags) add them to
+stapio_LDADD.
+
+Apart from being the "right" thing to do, this fixes build failures on systems
+such as current Ubuntu (which defaults to using --as-needed and similar) where
+link order is important.
