The `CONFIG_LINKER_SORT_BY_ALIGNMENT` config, which is enabled by default, causes the sections containing C++ exception handling information to be re-ordered for certain targets (in particular, the 64-bit arch targets). This effectively breaks the required "crtbegin.o -> others -> crtend.o" order and causes the address of the __EH_FRAME_BEGIN__ symbol to be invalid; thereby, causing C++ exception unwinding to fail. This commit adds SORT_NONE property to these sections in order to ensure that the linking order specified in the linker command line is maintained.
