As Paul already pointed out, you just can't do this.

# To match any target that has "pattern" in it. A simple testcase follows:
#       ====================== Makfile ================================
#       %.1.% : PAT_DEP_VAR = yes
#       first.1.1 :
#               @echo $(PAT_DEP_VAR)
#       second.1.2 :
#               @echo $(PAT_DEP_VAR)
# 
# The output of either "make first.1.1" or "make second.1.2" should yield
# "yes". In this case, I am not particularly interested in the/either "stem"
# (but note that the "prefix-stem" and the "suffix-stem" usually do differ).
# 
# Note that I cannot automatically generate a list of the possible targets
# from an "ls", since the files may or may not exist, and the combinations may
# be too many... So in other words, I cannot search a variable
# $(POSSIBLE_TARGETS) for a match.

I'm afraid you have to bite the bullet and use target specific variables
for each target:

   first.1.1 : PAT_DEP_VAR = success
   first.1.1 :
           @echo $(PAT_DEP_VAR)
   second.1.2 : PAT_DEP_VAR = success
   second.1.2 :
           @echo $(PAT_DEP_VAR)

Not too elegant, but does the job. If you're wanting to be fancy,
autogenerate that part of the makefile and include it in the master.
