Starting from the upcoming GCC release 10, the default of -fcommon option will
change to -fno-common. Due to this we're going to see a lot of build failures
in Mesa drivers like

multiple definition of `syncobj_handle'; src/amd/vulkan/9198681@@vulkan_radeon at sha/meson-generated_.._radv_entrypoints.c.o (symbol from plugin):(.text+0x0): first defined here
[  213s]
src/amd/vulkan/9198681@@vulkan_radeon at sha/radv_wsi_wayland.c.o (symbol from
plugin): in function `radv_GetPhysicalDeviceWaylandPresentationSupportKHR':

I'm wondering if there is already anybody working on fixing these issues or is
it recommended to workaround it by setting -fcommon manually somehow? How can
the latter be done when using meson/ninja as build tool?
