Sorry, I was under the assumption that the problem is not unique to the actual
variable in question.  That is, making any global variable non-static risks
having relocation fail.

I was looking for a more general explanation to the problem.  I was hoping that
someone who understood the relocation code well could explain to me, in
theoretical terms, how this could happen.

This is a new file that I haven't posted yet.  It is a replacement for
board/freescale/common/sys_eeprom.c.  It's currently undergoing internal review.
 That's why I asked for a general explanation.

Compiler: powerpc-linux-gnu-gcc (GCC) 4.2.1
Binutils: GNU ld (GNU Binutils) 2.18.50.20070820
