[Ada] Remove vxlink and vxaddr2line from this repository 

Those tools need a dedicated repository as they're VxWorks specific and
not related with the Ada front-end.

2018-12-11  Jerome Lambourg  <lambourg@adacore.com>

gcc/ada/

	* vxaddr2line.adb, vxlink-bind.adb, vxlink-bind.ads,
	vxlink-link.adb, vxlink-link.ads, vxlink-main.adb, vxlink.adb,
	vxlink.ads: Remove.
	* gcc-interface/Make-lang.in, gcc-interface/Makefile.in: Remove
	bits for vxaddr2line.

-- This program is meant to be used with vxworks to compute symbolic
-- backtraces on the host from non-symbolic backtraces obtained on the target.
-- The basic idea is to automate the computation of the necessary address
-- adjustments prior to calling addr2line when the application has only been
-- partially linked on the host.
-- Variants for various targets are supported, and the command line should
-- be like :
-- <target>-addr2line [-a <target_arch>] <exe_file> <ref_address>
-- <backtrace addresses>
-- Where:
-- <target_arch> :
-- selects the target architecture. In the absence of this parameter the
-- default variant is chosen based on the Detect_Arch result. Generally,
-- this parameter will only be used if vxaddr2line is recompiled manually.
-- Otherwise, the command name will always be of the form:
-- <target>-vxaddr2line
-- where there is no ambiguity on the target's architecture.
-- <exe_file> :
-- The name of the partially linked binary file for the application.
-- <ref_address> :
-- Runtime address (on the target) of a reference symbol you choose. This
-- name must match the value of the Ref_Symbol variable declared below.
-- A symbol with a small offset from the beginning of the text segment is
-- better, so "adainit" is a good choice.
-- <backtrace addresses> :
-- The call chain addresses you obtained at run time on the target and
-- for which you want a symbolic association.
-- TO ADD A NEW ARCHITECTURE add an appropriate value to Architecture type
-- (in a format <host>_<target>), and then an appropriate value to Config_List
-- array

-- VxLink is a helper tool used as a wrapper around g++/gcc to build VxWorks
-- DKM (Downloadable Kernel Modules).
-- Such DKM is a partially linked object that contains entry points for
-- constructors and destructors. This tool thus uses g++ to generate an
-- intermediate partially linked object, retrieves the list of constructors
-- and destructors in it and produces a C file that lists those ctors/dtors
-- in a way that is understood be VxWorks kernel. It then links this file
-- with the intermediate object to produce a valid DKM.
