Actually it's a bit more convoluted than that. Most distro prep -dbg packages,
which contain the debug symbols (i.e. build mesa and others with -g*). Last
time I've checked all of them did not bother having any checks for LTO & -g*
which will cause the issue :'(

Feel free to have it locally, but for now I would prefer if mesa opts-out. As
new and better gcc comes along my I will likely reconsider my statement :P
