sparc64: fix alignment bug in linker definition script
The RO_DATA section were hardcoded to a specific alignment in include/asm-generic/vmlinux.h. But for sparc64 this did not match the PAGE_SIZE. Introduce a new section definition named: RO_DATA that takes actual alignment as parameter. RODATA are provided for backward compatibility. On top of this avoid hardcoding alignment for sparc64 in reset of the script Fix is build-tested on sparc64 + x86_64. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
