sparc64: Kill annoying warning when building compat_binfmt_elf.o
GCC warns because some tests against 32-bit values never evaluate to
true due to how TASK_SIZE is defined.
I always wanted to mimick powerpc's definition of TASK_SIZE, which
is simply TASK_SIZE_OF(current) and that also fixes the warning.
