I'd like to take a deeper look at this, please hold.

It seems that mesa, for some reason, allocates a lot more RAM in qemuarm64
(150 Mb more or so), than it does in qemux86_64. I'll investigate.

Sadly, I can confirm: weston swelling to double size on qemuarm64 is caused
by this recent change in glibc:

+EXTRA_OECONF_append_aarch64 = " --enable-memory-tagging"

You can verify with this innocent looking program. Run 'free' while it is
running and compare with and without tagging:

main()
{
   for (int i=0; i<768; i++)
       calloc(1,262368);
   sleep(200);
}

I'll queue a revert.

I think we should disable this by default, its a good feature during
development though to catch memory bugs. So please turn it into a
PACKAGECONFIG which is disabled
by default instead of revert.

Right, I'll adjust to a PACKAGECONFIG. ARM folks should investigate what
looks like a copy-on-write breakage.
