As already posted: The problem lies in the output of "$(gcc -dumpmachine)". A 
look at the manual page (man gcc-4.0) says to me:

-dumpmachine
	Print the compiler's target machine (for example, i686-pc-linux-gnu)---and 
don't do anything else.

First look wether the option "dumpmachine" works by 
issuing "gcc -dumpmachine". If successful, have a look wether the 
corresponding path as expected by "/tools/$(gcc -dumpmachine)/bin/" really 
exists.

Nevertheless I'm afraid, that most likely "gcc -dumpmachine" will not work for 
you. But there are people on this list who for sure can help in that case.

BTW: Have a look at the manual page of bash - section "Command Substitution":

"Command substitution allows the output of a command to replace the command 
name. There are two forms: 

 
 $(command ) 
 or 
`command` 


 Bash performs the expansion by executing command and replacing the command 
substitution with the standard output of the command, with any trailing 
newlines deleted."

Bad idea! In case of such an obvious error, have a look at the LFS pages or 
ask for help.
