I don't really understand what you're trying to do; an example might help.

However, from what I do understand why don't you use recursive variable
names?  This feature is widely available in all versions of make and I
think it's going to be added to the standard:

  exe1_LIBS = -lfoo -lbar
  exe2_LIBS = -lbiz -lbaz

  exe%: ...
          ... $($@_LIBS)
