This causes the pseries boot wrapper build to fail with: /usr/bin/ld.bfd: arch/powerpc/boot/wrapper.a(crt0.o): warning: relocation against `_platform_stack_top' in read-only section `.text' /usr/bin/ld.bfd: error: read-only segment has dynamic relocations The pseries wrapper uses '-pie' to create position-independent code. However, crt0.S contains a pointer to '_platform_stack_top' in the .text section, which requires a dynamic relocation at runtime. This creates DT_TEXTREL (text relocations), which were allowed by default in binutils 2.45 and earlier (via implicit '-z notext') but are now rejected by binutils 2.46+. Add '-z notext' linker flag to explicitly allow text relocations for the pseries platform, similar to what is already done for the epapr platform. This restores the previous behavior and allows the boot wrapper to build successfully with binutils 2.46+.
