After some measurements it seems the problem was on layer 8. Taking your
crosstool configs I get both 32bit and 64bit non-debug builds finished
within 2 hours and the debug builds take both around 14 hours. What
probably happened was that I built a debug version of the cross-compiler
on my 32bit system, too but I did not use it but rather the non-debug
version. I realized that the path in my .mozconfig file did not point to
$HOME/x-tools where the debug version was but rather to an other where I
probably copied the optimized version to. Problem solved, thanks.

it's likely an fairly essential bridge to allow JavaScript to call native
code for speed critical things? I can ask the Mozilla guys now that we've
made contact.
Well, you could ask if it is expected that the Firefox built with the
cross-compiler crashes every time on startup if we disable ctypes in the
.mozcpnfig while this is not happening with a native built Firefox using
the same compiler (+ same version + same .mozconfig) (noting that the
latter is unusable though). That might be an interesting thing to know.

Thanks. Seems to be a good idea to me, yes.
