It is just a question of syntax.  You can set variables depending on the  
target they are for like this:

variant1: SRC = "foo.c"

variant2: SRC = "bar.c"

This syntax is limited to one varaible per line (at least I think so)

Your case should be written as:

target1: MCU = mega128
target1: SRC="this.c that.c ..."
target1: ASRC="this.S that.S ..."

target2: MCU=mega16
target2: ...

See the GNU Make Manual on topic "Target-specific Variable Values"

P.S. I had some nasty bugs in older versions of GNU make with a syntax like

target: FOO += toto.c

i.e. appending to a variable depending on the target.  It sometimes gave  
very strange results...
