libc: unsplit log message to to make it greppable in src

[emaste]

Summary

Also use func rather than hardcoding the function name. This code now fits in 80 columns without splitting the log message.

lib/libc/stdlib/cxa_thread_atexit_impl.c

Will __func__ be expanded to __cxa_thread_call_dtors ?

[dim]

lib/libc/stdlib/cxa_thread_atexit_impl.c

Nope, __func__ is always the name of the enclosing function, in this case walk_cb_call. @emaste maybe this will confuse people?

[emaste]

Ok, __cxa_thread_call_dtors is more useful for tracking this down so restore explicit function name (and just accept > 80 cols)

upload diff relative to main, not the fixup change

Looks good to me.
