Mark Johnston 9ddf3d342b Add relocation handling required for -zifunc-noplt to work on arm64.
Static relocations for the immediate operand of a branch instruction
must be applied.

In a patch which implements LSE-based atomic(9) operations using ifuncs,
-zifunc-noplt reduces system CPU usage during a buildkernel by several
percent.

Also fix elf_reloc_internal() to return an error if symbol lookup fails.
