[Qemu-devel] PATCH: fix undefined function errors

I ran into errors about undefined functions when building user-mode QEMU for ARM 
Linux after picking up a recent update from trunk.  The attached patch fixes the 
problem.

As I'm not a QEMU maintainer, someone who is will have to check this in....  or 
some alternate fix for the same problem, maybe.

	* linux-user/syscall.c (do_syscall):  Make #ifdef on
	TARGET_NR_inotify_init, TARGET_NR_inotify_add_watch, and
	TARGET_NR_inotify_rm_watch cases match that used previously 
	in the file, to avoid references to undefined symbols.
