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 Signed-off-by: Zhenhua Luo <zhenhua.luo@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com>
