load/store address overflow on binutils 2.14

[Atsushi Nemoto <anemo@mba.ocn.ne.jp>]

I'm trying binutils 2.14 (and binutils 2.14.90.0.5).  These versions
can not compile this inctruction.

        lw      $2, 0x80000000

$ mips-linux-gcc -c foo.s
b.S: Assembler messages:
foo.S:1: Error: load/store address overflow (max 32 bits)

Using such an immediate address for load instructions is legal?  I
found the error message in tc-mips.c and it looks like something
related to 64bit ABIs, but I just want to compile 32bit (standalone)
program.

Is this code really needed for 32bit ABI?

binutils-2.14/gas/config/tc-mips.c:6297
          else if (offset_expr.X_op == O_constant
                   && !HAVE_64BIT_ADDRESS_CONSTANTS
                   && !IS_SEXT_32BIT_NUM (offset_expr.X_add_number))
            as_bad (_("load/store address overflow (max 32 bits)"));
