AUTOTOOLS: More robust detection of inotify.
We checked only header file "sys/inotify" for detection whether inotify
works. Some platforms do not have built in inotify, but contain library,
which provides inotify-compatible interface.
This patch adds more robust detection of inotify in configuration time and
appends linker flags to Makefile if inotify is provided by library.
