Build fails due to undefined references in libmarlincore.so

[David Kiefer]

When trying to build marlin 879 on Ubuntu 12.04, linking of marlin fails with the following messages:

Linking C executable marlin
../libcore/libmarlincore.so.0.1: error: undefined reference to 'XParseGeometry'
../libcore/libmarlincore.so.0.1: error: undefined reference to 'g_module_open'
../libcore/libmarlincore.so.0.1: error: undefined reference to 'g_module_error'

../libcore/libmarlincore.so.0.1: error: undefined reference to 'g_module_name'
collect2: ld returned 1 exit status

And when continuing with make -k, there's also the following errors:
