Can you send me gcc's configure line for the sparc toolchain that you use?
I can confirm it also using our build system as well.
In file included from libc/sysdeps/linux/sparc/soft-fp/q_div.c:24:0:
libc/sysdeps/linux/sparc/soft-fp/quad.h:63:1: error: unable to emulate 'TF'
<snip>
if I can reproduce the error here (if you send the gcc configure line) I
can try to post a patch that handles the error...

Alternatively, the OpenWrt repo has sparc support since r24559, selecting the
sparc target and the uclibc git version will hit this issue.
Best regards,
