hppa/ELF: fix .text/.data interaction with .previous

For some ELF targets .text/.data are overridden. In that case
obj_elf_{text,data}() need calling, just like .code vectors to that
function for the remaining ELF targets.

While there also hand on the function arguments, even if right now
they're meaningless. This matches what other targets' code does.
