[Buildroot] [PATCH 4/8] poppler: add explicit libglib2 support

[Gustavo Zacarias]

Evince needs poppler-glib support (when poppler is enabled, for PDF
reading support), so add explicit handling to the package.
And poppler-glib requires cairo output, hence the conditional on both
libglib2 and cairo to enable it.
