yes, but i think this is initially hardcoded.

I talked to andyrtr about this and he said "unknown" was chosen because older 
versions of autotools could not hanlde "pc". I have looked into 
http://cvs.savannah.gnu.org/viewcvs/*checkout*/config/config/config.sub and 
there you`ll finde the following comment:

	# We use `pc' rather than `unknown'
	# because (1) that's what they normally are, and
	# (2) the word "unknown" tends to confuse beginning users.
	i*86 | x86_64)
	  basic_machine=$basic_machine-pc
	  ;;

Well I do not know how important this chost variable is. ;-) But after some 
research I would say that "x86_64-pc-linux-gnu" would be corrent nowadays. 
And btw: do you know any x86_64 machine which is not a pc?
