memory at the end of the kernel.

This helps reduce the SoC and board specific configuration required.

Correctly align the unwind tables. Without this clang may incorrectly align
them causing an alignment fault when producing a backtrace.

When DDB is enabled and we are building for the ARM EABI include the unwind
tables in the kernel.

Get rid of ARM_BIG_ENDIAN for good:
- remove leftovers in Makefile.arm
- Let ld use default output format instead of providing one in ldscript

Create a non-elf pure binary version of the kernel as well.

Use the address provided in the conf file, instead of hardcode 0xc0000000.

Add config magic for arm.
