   1 # This is a procedure to define the targets for building
   2 # the runtime.
   3 #
   4 # Argument 1 is the target triple.
   5 #
   6 # This is not really the right place to explain this, but
   7 # for those of you who are not Makefile gurus, let me briefly
   8 # cover the $ expansion system in use here, because it
   9 # confused me for a while!  The variable DEF_RUNTIME_TARGETS
  10 # will be defined once and then expanded with different
  11 # values substituted for $(1) each time it is called.
  12 # That resulting text is then eval'd.
  13 #
  14 # For most variables, you could use a single $ sign.  The result
  15 # is that the substitution would occur when the CALL occurs,
  16 # I believe.  The problem is that the automatic variables $< and $@
  17 # need to be expanded-per-rule.  Therefore, for those variables at
  18 # least, you need $$< and $$@ in the variable text.  This way, after
  19 # the CALL substitution occurs, you will have $< and $@.  This text
  20 # will then be evaluated, and all will work as you like.
  21 #
  22 # Reader beware, this explanantion could be wrong, but it seems to
  23 # fit the experimental data (i.e., I was able to get the system
  24 # working under these assumptions).
