    tc-pdp11.c: remove useless code
    
    if the condition is true then we know that str already points to a'\0' in the
    string passed to the function.  Since we know the latter part of the function
    doesn't modify that string, and str already points to a null byte there's no
    point in changing str to point to a literal empty string.
