This commit updates the Alpha linker to reject specific relocation types that cannot correctly refer to IFUNC symbols. Relocations such as R_ALPHA_BRADDR, R_ALPHA_BRSGP, general GP-relative relocations, and R_ALPHA_SREL* directly name the symbol, bypassing the IFUNC resolver. R_ALPHA_REFLONG only has a 32-bit field, insufficient for the resolver’s return address. These invalid relocations are now reported, allowing the linker to report all such errors in a single pass.
