This happens because the compiler has placed an offset to data in a 22-bit
immediate field of an instruction. During linking, the linker must update
the offset to its final value, which overflows the 22 bits.
Basically, an assumption made by the compiler is broken. You must take a
word-around to eliminate the message.
