lb1sf68.asm (PICCALL, PICJUMP): Use GOT instead of PC-relative addressing when compiling for uclinux PIC.

	* config/m68k/lb1sf68.asm (PICCALL, PICJUMP): Use GOT instead of
	PC-relative addressing when compiling for uclinux PIC.
	(__cmpdf_internal, __cmpsf_internal): Hide.
	(__cmpdf, __cmpsf): Use PIC call sequence.
