2:20, that's two hours and twenty minutes, to build and install here on 
an Atom N270 system.  2:06 for gcc6-aux, most of the rest for ncurses. 
That does not include distfile download time.  Disk space used was 252M, 
again not counting the distfiles.  For x86, the Atom is nearly 
worst-case, but I suspect the speed is similar to some of the ARM 
systems.

I tried to build it last night on a fast i7 system for comparison, but 
gcc6-aux had a build error at the very start.
