It means that the assembler can neither emit a literal value for
the expression (the address of the "subroutine" symbol), nor does
it have an available relocation type so that the linker can fill
in a value.  If the operand was declared as PC-relative (see
PCREL-ADDR), the assembler would be able to resolve the value at
assembly time (probably -2 or something like that).
