#4 Relocations done when building sandpoint

[Mark Brown]

When trying to build the ppcboot for sandpoint from current
CVS I get lots of cpmplaints from the assembler of the form:

cpu/mpc8240/start.S:709: Error: Relocation cannot be done
when using -mrelocatable

This bug does not occur when using 1.0.1, though there is
also a build problem there that I'm about to file a bug on. I'll
endeavour to produce a fix.
