[libvirt PATCH] Set -Wno-incompatible-pointer-types-discards-qualifiers
With CLang we're getting failures from cats in GLib macros
../dist-unpack/libvirt-6.10.0/src/util/vireventthread.c:35:1:
error: passing 'typeof (*(&g_define_type_id__volatile)) *'
(aka 'volatile unsigned long *') to parameter of type
'gsize *' (aka 'unsigned long *') discards qualifiers
[-Werror,-Wincompatible-pointer-types-discards-qualifiers]
G_DEFINE_TYPE(virEventThread, vir_event_thread, G_TYPE_OBJECT)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The cast is valid and there's no way for libvirt to workaround
the issue, so we must disable this CLang warning flag.
