Yes. I thought about this after I sent the last post.

I checked my logs and indeed, it is not compiled when using an LFS host.
I'm not sure what is wrong with KNOPPIX that it does not have putenv and
check wants to build it. configure runs:
ac_fn_c_check_func "$LINENO" "putenv" "ac_cv_func_putenv"
in order to determine if it is present and it should be in libc-2.17.so.
Does KNOPPIX 6.7.1 meet all the requirements of the Host System
Requirements? Look especially for glibc. For me, I did:
$ nm /lib/libc-2.17.so|grep putenv
0000000000037500 T putenv
