c0e70b2543 Tweak sparc32 longjmp to not store a dummy frame pointer onto the stack. 
* sysdeps/sparc/sparc32/__longjmp.S: Unwind in the 'thread' path
	using a normal save/restore sequence, rather than allocating a
	dummy stack frame just to store a frame pointer and restore.
	* sysdeps/unix/sysv/linux/sparc/sparc32/____longjmp_chk.S: Likewise.

d510c12326 Use PI_STATIC_AND_HIDDEN on sparc if we universally use GOTDATA relocs. 
* sysdeps/sparc/elf/configure.in (PI_STATIC_AND_HIDDEN): Define if
	both binutils and gcc support GOTDATA.

0722d7c2ac Explain why we don't make use of RDPC in the sparc PIC register setup. 
* sysdeps/unix/sparc/sysdep.h: Document why we don't use
	"rd %pc" in the PIC register setup sequences.
