Re: [libvirt] [PATCH v3 01/19] build: probe for glib-2 library in configure

Prepare for linking with glib by probing for it at configure time. Per supported platforms target, the min glib versions on relevant distros are: RHEL-8: 2.56.1 RHEL-7: 2.50.3 Debian (Buster): 2.58.3 Debian (Stretch): 2.50.3 OpenBSD (Ports): 2.58.3 FreeBSD (Ports): 2.56.3 OpenSUSE Leap 15: 2.54.3 SLE12-SP2: 2.48.2 Ubuntu (Xenial): 2.48.0 macOS (Homebrew): 2.56.0 This suggests that a minimum glib of 2.48 is a reasonable target. This aligns with the minimum version required by qemu too. We must disable the bad-function-cast warning as various GLib APIs and macros will trigger this.
