Not as long as I have been using the wiki instructions.
The other point is, while it would be OK to
mention crosstool-ng in the Wiki, or even write an introduction on its use,
replacing the existing instructions with those for a third-party tool would be suboptimal IMHO. It would mean that we would have to handle any issues encountered with present
and future versions of crosstool-ng here in the forum. By
not relying on crosstool-ng, we
only have to handle problems with the cross-building process itself, and the occassional "why do I need a crosscompiler in the first place" question. I also think that the current way is more... instructive (no pun intended) as to what's really going on.
I don't say that these are "killer arguments", just that there are benefits to describing the "manual" path.
