If CONFIG_RELOCATABLE is enabled, call relocate_kernel.
This function will return the entry point of the relocated kernel if
copy/relocate is sucessful or the original entry point if not. The stack
pointer must then be pointed into the new image.

When debugging a relocated kernel, the addresses of the relocated
symbols and the offset applied is essential information. If the kernel
is compiled with debugging information, then print this information
during bootup using the same function as the panic notifer.

(mark as 0 length) the relocation sections added to vmlinux.
When vmlinux is passed to the boot makefile for conversion into a boot
image the now empty relocation sections will be removed and the
populated relocation table will be included in the binary image.

32bit kernel O32 userspace before: 48
the syscall return value when skipping,
since both would need to set the same register. Therefore modify that
test case to just detect the skipped test.
Tested on MIPS32r2 / MIPS64r2 with O32, N32 and N64 userlands.
