In binutils-2.25, the _GLOBAL_OFFSET_TABLE_ symbols defined by PROVIDE in u-boot.lds overrides the linker built-in symbols (https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff ;h=b893397a4b1316610f49819344817715e4305de9), so the linker is treating _GLOBAL_OFFSET_TABLE_ as a definition into
the .reloc section.
To align with the change of binutils-2.25, the _GLOBAL_OFFSET_TABLE_ symbol should not be defined in sections, and the symbols in linker generated .got section should be
used(https://sourceware.org/ml/binutils/2008-09/msg00122.html).
Fixed the following build errors with binutils-2.25: | powerpc-poky-linux-gnuspe-ld.bfd: _GLOBAL_OFFSET_TABLE_ not defined | in linker created .got

What happens when we use older binutils?
[Luo Zhenhua-B19537] I verified the u-boot build for p4080ds(e500v2) with binutils-2.23.2, the build passed.
I'd like some run-time testing too please :) Thanks! [Luo Zhenhua-B19537] I did sanity test for the u-boot on p4080ds, it works normally.
The log files are attached.
Best Regards,
Zhenhua
