Rework sparc PIC macros so crt{i,n}.S can use them too.
* sysdeps/unix/sparc/sysdep.h (SPARC_PIC_THUNK): New macro. (SETUP_PIC_REG): Use SPARC_PIC_THUNK and don't save and restore %o7 across the call. (SETUP_PIC_REG_LEAF): Do %o7 save/restore in this new macro instead. * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h: Use SETUP_PIC_REG_LEAF. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h: Likewise. * sysdeps/sparc/crti.S: Use SETUP_PIC_REG. * sysdeps/sparc/crtn.S: Likewise.
