OpenJDK 6 builds on mips, using gcj to bootstrap

[Matthias Klose <doko@ubuntu.com>]

OpenJDK 6 currently ftbfs on mips*, using gcj-4.6. Please could a mips porter 
please check if gcj-4.7 from experimental is good enough to build OpenJDK 6? 
gcj-4.7 won't be installed on the porter machines, so this to be done by 
somebody with access to a mips machine.

Thanks, Matthias
