It's not within range of "li".  I wonder if whatever non-"STD" binutils
this is supposed to be used with is rewriting it into an lis
instruction.  This sort of external dependency is a poor fit for the
randconfig concept (plus, shouldn't the symbol be indicating what
binutils you're supposed to have rather than anything that isn't
"standard"?).

In any case, you could use something like LOAD_REG_IMMEDIATE().
