Compile issues

Tested on Ubuntu 9.10 (Karmic) and 10.04 (Lucid beta) – works fine according to build.sh script.
Older versions of Ubuntu weren’t tested by me, so that I can’t prove it’s full compatibility.

On older versions of Ubuntu, it’s not possible to run ./prepmake.sh (it exists with an error).
Solution is to delete NpapiPluginTest:

cd firebreath/
rm -rf src/NpapiPluginTest/*
