Fix bugs in sparc PLT profiling register management, and add sparc sotruss support.
* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Protect local variables with appropriate CPP guards. * sysdeps/sparc/sparc32/dl-trampoline.S: Propagate the stack_ptr from the frame pointer, not the stack pointer. Correct layout comments. Fix test on resulting framesize and the management of the outregs buffer for pltexit. Preserve floating point return values across _dl_call_pltexit call. * sysdeps/sparc/sparc64/dl-trampoline.S: Fix test on resulting framesize and the management of the outregs buffer for pltexit. Preserve floating point return values across _dl_call_pltexit call. * elf/sotruss-lib.c (la_sparc32_gnu_pltenter, la_sparc64_gnu_pltenter, la_sparc32_gnu_pltexit, la_sparc64_gnu_pltexit): New functions. (print_exit): Fix format string for return register value.
