BUILD: Fix a typo in inotify.m4 This typo prevented HAVE_INOTIFY from ever being set and as an effect, prevented /etc/resolv.conf inotify detection from working Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com> Reviewed-by: Fabiano Fidêncio <fidencio@redhat.com>

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.
