netchild ec68a94632 Revert r206179 (by imp) and do something similar which is more consistent
with all other corresponding CTF places by changing the corresponding
code which is generated by config(8). Or in short, move the '@' from
the variable definition to the use of the variable. [1]

While I'm here break up a long line. [2]
