Hello,

on sh4, libuv1 with io_uring support enabled often causes cmake to crash [1]:

-- Performing Test C_COMPILER_SUPPORTS_-Werror__undefined-inline

This can be worked around by just disabling io_uring support on sh4:

Thus, could you please include this patch for the next libuv1 to fix these crashes?

Thanks,
