The switch from archive libraries to partial linking has introduced a number of problems, that are non-trivial to solve. For example, it is no longer possible to include individual object files in the linker script as we did before for example in the case of boards with embedded environment to fill up the gap caused by the need to align the environment on flash erase block boundaries.
The best (but unfortunately not easiest) approach to address this problem is to enable -ffunction-sections (and -ffunction-sections) so
's/function-sections/data-sections/' in the 2nd location above.

The above changes already exist in arch/powerpc/cpu/mpc85xx/config.mk and arch/powerpc/cpu/mpc86xx/config.mk. It'd be nice to remove those references in this patch so they aren't duplicated.
Best, Peter
