GTK_THEME instructs gtk to use its built-in theme. Otherwise
gtk attempts to use the theme from the host, which may be from
a totally mismatching gtk version.

On the other hand FONTCONFIG_PATH tells it to use the host fonts,
as providing fonts in the native sysroot and instructing the components
to use them is a lot more tricky.

GDK_PIXBUF_MODULE_FILE is set, because otherwise qemu works but
fills stdout with error messages, which eventually fill the pipe
they go into. That pipe is read from only when qemu exits (to
collect any error messages) by runqemu script. The pipe fill-up
causes the qemu process to lock up.
