How a pattern matches multiple files

[lijh.8]

Hi community,


The builtin pattern rule for compiling 
%.o: %.c
describes that one object file depends on one source file.


But how can the linking rule match multiple object files
%: %.o 
and work for
x: x.o y.o z.o 


We did not and could not write it like:
%: %.o %.o ... 


right?


Thanks
