This is not a good question to ask IMVHO.  If we know of certain
features that will be in upcoming OS's, we should strive to support
them.  Note that Libtool might be part of a longer development tool
chain, and starting support only after release might delay dependent
software unduly.  Example: LAM needs Libtool, provides MPI.
$simulation_code needs MPI.  Waiting for respective releases to happen
(esp. given the frequency of Libtool releases) is not fun.

OTOH, you are quite right that we should not support _speculative_
features.  (For the problem at hand, I should admit that I do not know
about speculativeness of the feature, but trust Peter's judgement.)

ACK, thanks for mentioning this.  Creating a suitable hardcode_*
variable for this should not be hard.
