Pass local symbols relocations in both passes and provide the kobj_reloc
implementation visibility of these relocations.

Currently all implementations resolve local symbol relocations in the first
pass and simply skip them in the second. The RISC-V implementation will
make use of this visiblity.

Switch earmv6{,hf}eb to BE8 in kernel side.

My strategy here is to define _ARM_ARCH_BE8 macro in arm/cdefs.h, if
__ARMEB__ && _ARM_ARCH_6.

Use this macro to determine whether system is compiled for and running on
BE8 mode or not.

Note that, for __ARMEB__, some conditions become compile-time constants
determined by _ARM_ARCH_BE8 macro, e.g., whether BE8 or BE32 are accepted
as a userland binary, or unaligned memory access is possible or not.

Remove some unnecessary ones while I'm here.

Handle absolute relocations coming from the kernel: preserve SHN_ABS in
the kernel and module symbols, and when relocating a symbol that has
SHN_ABS, take its value as-is and don't return an error if it equals zero.
