t-constant fail i686-darwin10

[Torbjorn Granlund]

This looks like non-clean builds.

Please make sure to start with a clean directory (or at least do a 'make
distclean' between builds).

Please follow up on this so that we know if this is indeed the problem.
If you get the reported error from a clean build, please carefully follow
the instructions here: http://gmplib.org/manual/Reporting-Bugs.html
