Your patch simply deactivates our libc plugin mechanism for write(). I
admit, that we currently do not support writes to stdout and stderr
out of the box _and_ that the current error message is a bit
misleading. We _do_ support write() but not to the given fd. I will
fix this soon.

Please read more about the plugin concept here

and in the sources of libc_lwip.

Why do you need this additional linebreak? PERR() adds it in
base/include/base/printf.h:73 to the output.
