[PATCH] microblaze: don't index the local symbol cache with a global symbol index

Sam Price has submitted a patch to fix an issue in microblaze_elf_relax_section where a bounds check was dropped during a code copy, leading to an out-of-bounds read that could corrupt relocation addends. The patch reintroduces the missing guard, preventing silent miscompilations and ensuring data integrity, as confirmed by new test cases.
