[Qemu-devel] [PATCH] Fix conditional compilation case CONFIG_INOTIFY && !CONFIG_INOTIFY1.

[takasi-y]

There is undefined reference to sys_inotify_init1() at do_syscall() when
CONFIG_INOTIFY=y and CONFIG_INOTIFY1=n.

We should undef TARGET_NR_inotify_init1 if CONFIG_INOTIFY1 is undefined, as
it seems to be the strategy of conditional compilation here.
