It does not matter: This command links an absolute path 
${CLFS}/cross-tools/${CLFS_TARGET}/usr to
a relative path ".", but the relative path is relative to the second 
argument's directory. So it does not matterwhere this command is issued...
(you may check that this command does what you want by issuing
"ls -l ${CLFS}/cross-tools/${CLFS_TARGET}/usr" after issuing it)

Nothing. The patch will be applied much later in Chapter 5 (section 
5.7). It cannot be applied before you unpack the iana-etc tarball anyway 
(read again the "Important" notes in 4.1 introduction...)
