Since 9c8addbc1cd414711310c5a47693f5b0f0b9be3a (2.25) when building for sparc64
the build assumes VIS support (v9a).

What does that mean? Support for SPARC V9 was silently dropped?

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

I just recalled that the ifunc support was done for vis3, so it was not
useless.

Hmm, I'll have to check what's the oldest UltraSPARC CPU that supports v9a and
VIS.
