media-sound/glame fixed problem with newer guile

Without this patch, and using guile-8.5* and compiling media-sounds/glame with USE=gnome, I and another person got the following compile error:

glame_console.o: In function `port_register':
/var/tmp/portage/media-sound/glame-2.0.1/work/glame-2.0.1/src/gui/glame_console.c:63: undefined reference to `GLAME_NEWCELL'
