Qt 4.8 GCC 4.7 fixes

This change introduces two new patches to Qt 4.8. One prevents the build
system from using the -fuse-ld=gold GCC flag as this isn't upstream and
therefore not supported by many toolchains out there. The second patch
fixes a compile time error when using toolchains based on GCC 4.7.
