Makefile: Tell GNU make to delete rule outputs on error (#15474)
Add .DELETE_ON_ERROR to the "build.make" files that contain the actual build rules that generate files. This tells GNU make to delete the output of a rule if the recipe modifies the output but returns failure. This is particularly useful for custom commands that use shell redirection to produce a file. Do not add .DELETE_ON_ERROR for Borland or Watcom make tools because they may not tolerate it and would not honor it anyway. Other make tools that do not understand .DELETE_ON_ERROR will not be hurt.
