When reconfiguring an MSVC -release build with 'cmake .' after a full build, instead of being a no-op, it rebuilt everything. This happened because of CMAKE_CXX_FLAGS_RELEASE being accidentally modified on each reconfiguration, resulting in extra whitespace being added to the compiler command line rules. Specifically, this was because we always added '-O2 -Ob3 ' as a string to the compiler flags, but due to stripping, always tried to remove only '-O2 -Ob3' (no trailing white space) when removing the optimizations flags, resulting in an extra white space for each run. Remove the trailing white space after '-Ob3 '.
