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.
