PR3835: Populate unique SystemTap suffix from configure

2021-02-21  Andrew John Hughes  <gnu_andrew@member.fsf.org>

	PR3835: Populate unique SystemTap suffix
	from configure
	* NEWS: Updated.
	* acinclude.m4:
	(IT_DETERMINE_VERSION): Update JAVA_VER
	to match this version of IcedTea (11).
	Introduce JAVA_SPEC_VER, which is no
	different here, but will be for
	IcedTea <= 3 (OpenJDK <= 8)
	* tapset/hotspot.stp.in,
	* tapset/jstack.stp.in:
	Replace "end11" with "end@JAVA_SPEC_VER@"
	so that the unique suffix is completed
	by configure.
