You can compile with GCC 4.8 if IndexedDB and FTL JIT are disabled. However this brings a degradation of user experience, especially in case of IndexedDB which was supported in previous versions. Therefore you have 3 options: 1) Disable these features and build limited version using GCC 4.8; 2) Provide patches that fix compilation with GCC 4.8 and these features enabled (it's broken now because GCC 4.8 fails to compile legal C++11 construction, namely expansion of vararg template parameter pack inside lambda expression; 3) Use a different compiler to build QtWebKit package which still can be binary compatible with the rest of the system.
