[Qemu-devel] [PATCH 1/9] target-arm/arm-semi.c: Fix broken SYS_WRITE0 via gdb

[Peter Maydell]

A spurious trailing "\n" in the gdb syscall format string used
for SYS_WRITE0 meant that gdb would reject the remote syscall,
with the effect that the output from the guest was silently dropped.
Remove the newline so that gdb accepts the packet.
