Hi Henri,

I have submitted a correction that fixes the following build errors:

The problem is that the detection for when to use
langtools stub files wasn't complete. It can detect
if you are using a 1.6 jdk to bootstrap but it can't detect
if you are using an older 1.7 jdk to build. There is
information about how langtools build works in
Jonathan Gibbons blog page here:

http://blogs.sun.com/jjg/entry/building_javac_for_jdk7

I have expanded the test which detects for a recent jdk
so that the stub files are built if building with an older
1.7 jdk. With this fix I can now build on PPC again with
an older 1.7 jdk.

I've cc'ed the langtools list so the fix can be considered
upstream.
