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.
