Add VTable menu, FLASH as default, remove Makefile

Convert from manual "make" operated app.ld creation to runtime creation
whose options are selected from the build menu.

Use a prelink recipe to create the output app.ld file each run, without
need for any special tools.

Update the boards.txt.py script to generate this new config.
