ppc: Check for compilers that don't support relocation
Certain ppc compilers are known not to generate the .fixup section
properly. The .fixup section is necessary to create a relocatable
U-Boot image. A basic check for the existence of the .fixup section
should hopefully catch the majority of broken compilers which don't
support relocation.
