* Drop baselibs.conf file and generate it in specfile based on build flavor.
* Add glew-rename-EGL-library.patch: Append suffix to shared library built with EGL support to allow parallel installation with the GLX compatible flavor
* Pass linker flag -Wl,--version-script to handle scenario where both EGL and GLX symbols may be required.
* Use bcond_with(out) to enable/disable egl instead of 'bcond egl 1 (0)' for compatibility with Leap.
* Revise BuildRequires and Requires appropriate to each flavor.
* devel pkg: Promote pkgconfig(glu) from Recommends to Requires; it is anyway auto-required because it is listed as a dependency in glew's pkgconfig file.
