Compilation failure using platform-ststm32 10.0.0

Fixed by adding

        "product_line": "STM32F072XB"

in the board’s JSON file. I’ll do a PR.

Boards now declare their series, and the builder script uses that to get the startup assembler file

          PRODUCT_LINE = board.get("build.product_line", "")
          assert PRODUCT_LINE, "Missing MCU or Product Line field"

          def prepare_startup_file(src_path):
              startup_file = os.path.join(src_path, "gcc", "startup_%s.S" % PRODUCT_LINE.lower())
              # Change file extension to uppercase
              if not os.path.isfile(startup_file) and os.path.isfile(startup_file[:-2] + ".s"):
                  os.rename(startup_file[:-2] + ".s", startup_file)
              if not os.path.isfile(startup_file):
                  print(
                      "Warning! Cannot find the default startup file for `%s`. "
                      "Ignore this warning if the startup code is part of your project." % MCU
                  )

so the startup file for the STM32F072VBT6 you need is

And thus that product_line value.
