Linux Build

Fixed issues from nokia-developer fork for building on Linux and alternate WTKs (where WTK is in /opt/WTK2.5.2 and antenna's jar is in /path/to/antenna)

$ export WTK_HOME=/opt/WTK2.5.2

$ cd UI

$ ant -f antenna-build.xml -lib /path/to/antenna

$ cd ../IO

$ ant -f antenna-build.xml -lib /path/to/antenna

$ cd ../Ports/MIDP/IO

$ ant -f antenna-build.xml -lib /path/to/antenna

$ cd ../Ports/MIDP/UI

$ ant -f antenna-build.xml -lib /path/to/antenna
