Don't expose vaddr_t or register_t to userland.  The gdb configure script

Add imx6sx dtb files for BE too

(skrll)

Fix build after previous. m68k uses symnum instead of symidx.

(skrll)

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.
