[oe] [meta-gnome][PATCH 20/20] metacity: allow for warnings during compilation

[Khem Raj]

From: "Slater, Joseph" <joe.slater at windriver.com>

Add a PACKAGECONFIG option which lets us permit warnings during
compilation until warnings from new compiler versions are
dealt with.

enable the packageconfig by default since we default to gcc8
which produces these warning
