Add a stp file for usage from build directory
For systemtap the location of the process being tapped is crucial, as a result the existing stp file requires installation for use. There are now two files: $(TARGET_DIR)/$(QEMU_PROG).stp-installed: copied to $(tapdir)/$(QEMU_PROG).stp $(TARGET_DIR)/$(QEMU_PROG).stp: pointing to the built binary, usable without installation To use: stap -I $(TARGET_DIR) ...
