Instead of using the ARM builtin linker script for GNU ld, use the new unified one instead. This will allow us to increase the section alignment for DXE_RUNTIME_MODULEs, which is a prerequisite for enabling the UEFIv2.5 Properties Table memory protection feature.
Also, remove the -mword-relocations GCC option, since we now fully support all relative and absolute 32-bit ARM/ELF relocations.
