To avoid it, this patch uses the linker option --wrap to replace all
the internal libc.so .udiv calls to the wrapper __wrap_.udiv. Along
with strong alias in the udiv implementations, it makes linker do
local calls.

I think we already use a different mechanism for a similar purpose, viasysdeps/generic/symbol-hacks.h. Maybe it's possible to reuse that?


Thanks,
Florian
