[PATCH v2 46/50] target/m68k: Build 'gdbstub.c' once for system single binary

Posted by Philippe Mathieu-Daudé 1 month ago

There is a single qemu-system-m68k binary, but by moving
'gdbstub.c' in the target_common_system_arch[] source set
the resulting object can be linked into a single qemu-sytem
binary.
