   Note that the 'OVERLAY' command is just syntactic sugar, since
everything it does can be done using the more basic commands.  The above
example could have been written identically as follows.

       .text0 0x1000 : AT (0x4000) { o1/*.o(.text) }
       PROVIDE (__load_start_text0 = LOADADDR (.text0));
       PROVIDE (__load_stop_text0 = LOADADDR (.text0) + SIZEOF (.text0));
       .text1 0x1000 : AT (0x4000 + SIZEOF (.text0)) { o2/*.o(.text) }
       PROVIDE (__load_start_text1 = LOADADDR (.text1));
       PROVIDE (__load_stop_text1 = LOADADDR (.text1) + SIZEOF (.text1));
       . = 0x1000 + MAX (SIZEOF (.text0), SIZEOF (.text1));
