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 an 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 thesse 2 sections to satify the alignment requirement on RV32. This would break the assumption of the prelink process and generate an unbootable image.

--- This fix should go into the v2023.07 release.
