ant 1.7.1 and make 3.81

[Kelly O'Hair]

It appears that a problem with ant 1.7.1 can potentially impact the  
open jdk builds, see
https://issues.apache.org/bugzilla/show_bug.cgi?id=43114 for more  
information.
The potential for missing package-info.class files seems high, and the  
latest jaxws
sources run into this problem.

Since I hate to move backwards (to 1.7.0) I'd like to propose that the  
jdk builds move
to ant 1.8.0 as soon as possible, and that the sanity check be changed  
to require 1.8.0.
(openjdk6, openjdk7 and jdk7).
While I'm there, I'd like to also advance the 'make' version required  
to 3.81.

I suspect that the make 3.81 requirement is no big deal for the Linux  
people, but may
complicate lives a little for Windows and Solaris people.

The ant 1.8.0 issue may be more complicated for Linux users, since it  
likely will not
be available in rpm/deb package form right away, but the download and  
install is trivial:

Sorry about this disturbance, but this seems like the best course.
