Sure, as mentioned in my previous response, it was only available for 
the branched versions, but not available anymore for v5.2.0 and v6.1.0 
or top of master, which are the latest ones I have been testing.

I did see also problems with lto when compiling for arm, so I tend to be 
away from them, but I did try it as I assumed people use it in general.
