At present fputc() is used before the console is available, then write()
is used. These are not compatible. Since fputc() buffers internally it is
better to use the write(), so that a partial line is immediately
displayed.
This has a slight effect on performance, but we are already using write()
for the vast majority of the output with no obvious impacts.
