There isn't one. The semihosting ABI allows the guest to either
(a) open a file (it chooses the filename) or
(b) open the terminal (which is QEMU's stdin/stdout)
QEMU implements this, so it's up to your guest OS where its
logging goes; if it uses the terminal (which is the usual thing)
you can redirect QEMU's stdout using the usual shell redirections.
