I don't think it was even supported [1], we have VIS code forever:

$ git grep "fzero" sysdeps/sparc/sparc64/
sysdeps/sparc/sparc64/fpu/multiarch/s_lrint-vis3.S:     fzero   ZERO
sysdeps/sparc/sparc64/fpu/multiarch/s_lrintf-vis3.S:    fzeros  ZERO
sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyint-vis3.S: fzero   ZERO
sysdeps/sparc/sparc64/fpu/multiarch/s_nearbyintf-vis3.S:        fzeros  ZERO
sysdeps/sparc/sparc64/fpu/multiarch/s_rint-vis3.S:      fzero   ZERO
sysdeps/sparc/sparc64/fpu/multiarch/s_rintf-vis3.S:     fzeros  ZERO
sysdeps/sparc/sparc64/fpu/s_lrint.S:    fzero   ZERO
sysdeps/sparc/sparc64/fpu/s_lrintf.S:   fzeros  ZERO
sysdeps/sparc/sparc64/fpu/s_nearbyint.S:        fzero   ZERO
sysdeps/sparc/sparc64/fpu/s_nearbyintf.S:       fzeros  ZERO
sysdeps/sparc/sparc64/fpu/s_rint.S:     fzero   ZERO
sysdeps/sparc/sparc64/fpu/s_rintf.S:    fzeros  ZERO
sysdeps/sparc/sparc64/memset.S: fzero           %f0
sysdeps/sparc/sparc64/memset.S: fzero           %f2
sysdeps/sparc/sparc64/sfp-machine.h:      __asm__ __volatile__("fzero
%%f62\n\t"                        \
sysdeps/sparc/sparc64/sfp-machine.h:  __asm ("fzero %%f62\n\t"=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20
                \

(So all the work I did for the vis3 ifunc support is pretty much useless)
