The program is run each time because the result can change between
multilib runs.  I once played with a mechanism that would clear out
the cached value each time a new test directory was run; even better
would be clearing it out between multilib runs, but I didn't find a
place to do that.

If effective-target values are being used more frequently I'll take
another look at cachine their values.
