Comment(by ln5):

 It has nothing to do with GNU Make.  One could argue that Automake is
 wrong here but I haven't looked into it.  They seem to warn like this when
 you do non-portable things if I understand things correctly, which might
 be a hint that this is not a good idea.  I have tested with GNU make and
 BSD make (netbsd) but only with a recent version of each.

 Another option, as discussed with Sebastian on #tor-dev the other day,
 would be to set the makefile variables using this expansion thing within
 the 'if USE_ASCIIDOC' clause.  A  bit cludgy, admittedly.

 I've pushed the s/:=/::=/ change to my makefile-var-exp in case you'd like
 to merge.  I hope that branch is in proper shape, please tell if it's not.
 We don't need another changes file, do we?
