gui/Makefile fix, change ordering of linker options

gui/Makefile fix, change ordering of linker options

When trying to compile on my Ubuntu 12.04 LTE system, I received a lot of linker errors.
After changing the order of linker options make k8055gui succeeded 
and the gui works on my system. If no degradation on wheezy is observed, I propose to integrate my bug fix.

Thanks for your great work!
