Insight debugger

["Anthony Tonizzo" <atonizzo at google dot com>]

I have added support to build the insight GUI for gdb
within crosstool. The building is enabled by the
--insight switch (just like --gbd builds the gdb debugger.)

Notice that because insight already contains gdb,
the --gdb switch is not needed to compile insight.

The default version for gdb has also been bumped up to
6.8 from 6.3.

Cheers!
Anthony Tonizzo
