Fixed xinerama detection

Browse Source 
As reported by David Maciejak, when libXinerama was not found on the
system, the configure script still tried to search for associated
header and stopped all with unclear message.

The proper behaviour that was expected is to accept silently that
libXinerama may not be missing, and only stop compilation when the lib
is present but not its header.
