Looks like upstream forgot that OGRE_GCC_VERSION (the CMake variable) is
just the version, not multiplied by 100 like OGRE_COMP_VER (the C
macro), so libatomic never gets enabled. Fix attached.
Fix version check for enabling libatomic: OGRE_COMP_VER (C macro) is multiplied by 100, OGRE_GCC_VERSION (CMake variable) isn't.
