Same reason as cc_o. For both of these variables, the value will
contain $@ which make expands to the target being built. In the shell,
$@ expands to all arguments of the script/function. Passing the
filename as argument to a function and, within the function, expanding
the variable twice (eval provides a second expansion) gives the same
result as in make.
CC_E isn't currently used in the makefiles, but I have some plans...
