Your error message makes perfect sense. The rule tree for the target 
"all" is incomplete. From the make.info document:

`No rule to make target `XXX'.'
`No rule to make target `XXX', needed by `YYY'.'
      This means that `make' decided it needed to build a target, but
      then couldn't find any instructions in the makefile on how to do
      that, either explicit or implicit (including in the default rules
      database).

I *know* the following Makefile works. Save it as "Makefile", 
capital-M. Also either create an empty file named ".depend" (dot 
depend) or comment out the last line. If you "make depend" then a new 
.depend will be created including all the #include dependancies it 
found in your sources. Make sure the indented lines are indented with 
tabs. Some makes are sensitive, some are not. I forgot which way GNU 
make permits/requires.

Very little editing would be needed to convert this to your project. 
Just the MCU line, SRCS, and change "object.elf", "object.bin", and 
"object.list" if you don't like that name for the final product.
