[PATCH] Add a configure option for SELinux support

[PATCH] Add a configure option for SELinux support

[Sergey Kvachonok]

./configure --without-selinux :: unconditionally disable SELinux support

./configure --with-selinux :: enable SELinux support and abort if
libselinux is not found

When no configure option is specified the current libselinux
autodetection behaviour is preserved.
