In current linker script both .efi_runtime_rel and .rela.dyn sections are of RELA type whose entry size is either 12 (RV32) or 24 (RV64). These two are arranged as a continuous region on purpose so that the prelink-riscv executable can fix up the PIE addresses in one loop.
However there is an 'ALIGN(8)' between these 2 sections which might cause a gap to be inserted between these 2 sections to satisfy the alignment requirement on RV32. This would break the assumption of the prelink process and generate an unbootable image.
