build: remove glib dependency

We no longer require glib, yeah! Drop the mandatory glib dependency from
all build-files. Notice that there is not a single dependency, anymore,
except for libc.

We still have a not-mentioned pango dependency but this can be replaced
with freetype or a static font renderer so we currently do not care.
