Like I told you before, use diet with the -v option to see what compile
and link options it uses:

$ diet -v cc *.o
cc -nostdlib -static -L/opt/diet/lib-i386 /opt/diet/lib-i386/start.o *.o
-isystem /opt/diet/include -D__dietlibc__ /opt/diet/lib-i386/libc.a -lgcc

As you can see and were told before, more than just linking to libc.a is
needed, especially for compilation!

But it's better to just use the wrapper instead, as it may do other things
as well or change in the future. What is wrong with doing e.g. CC=diet cc
in your Makefile? Is it that it hardcodes the paths what makes it unsuitable
for your use? Then use the non-install version ./bin-i386/diet in the source
tree and distribute that together with at least diet's include files and libs.
