I think it’s fairly accurate to say that there isn’t a global setting, and it seems to be libc specific.
So there isn’t a configuration setting besides the one you noted for glibc.

For uClibc(-ng), there is CT_LIBC_UCLIBC_DEBUG_LEVEL.

And I’m guessing the same solution for glibc for musl-libc and newlib.

It would be fairly simple to add debugging options to the other LIBCs so they also have debugging options.
