  set value x = 1;   
else  
  set value x = 2;  
endif

In addition to the correct answer given above:if you want to check if x=4 or x=6

ifeq ($(x),$(filter $(x),4 6))   
   x is either 4 or 6. do whatever you like with it
else  
   x is neither 4 nor 6  
endif

Alternate answer is:

ifneq (,$(filter yes,$(cond1) $(cond2)))   
   x := 1
else  
   x := 2
endif
