This allows full ASLR (address space randomization) for all binaries without

While I am still fixing some stragglers where the default did not trigger,
and subtracting the packages where PIE was too tricky currently (emacs,
qemu, small number of others), I would estimate a 97% coverage at
this time. An rpmlint check will be added.

Finally. :) Great achievement! Thanks!

Ubuntu compiles the games as PIE since around 2012 already. With ugtrain
