This usually indicates /tools/bin/env is linked incorrectly.

I'd bet this is due to the same problems mentioned below...

No you didn't, as your variables below clearly indicate. For example, 
you apparently added "frenchslack" to the CLFS_TARGET vars...and a 
number of other changes.

If this is the env for the clfs user (as the indicated by the existence 
of AS, LD, CC, etc...vars), the PATH is incorrect, main problem being 
that /cross-tools/bin isn't anywhere to be found, which is likely the 
main source of all your problems.

Never mind the previous comment about clfs user, as apparently you 
aren't using it, despite your previous claim to be following the book.

There's one problem right there - Bash in /tools is linked to the host, 
and I bet so is everything else (such as Coreutils, which would explain 
the /tools/bin/env issue above). My guess your messing with various env. 
vars (and/or not bothering to set the right PATH) has messed things 
up...either that or it is due to even more deviations from the book that 
you haven't mentioned. All I can suggest is to rm -rf /{cross-,}tools/*, 
go back to the beginning and *actually* follow the book's 
instructions...all of them...
