armv7: fix relocation skip

I doubt the stack_setup() was defective before:
we load the current location of _start and compare against destination
of relocate_code(). If we are already there we shoud skip the
relocation and jump over to clear_bss. Before the clear_bss was also skipped.

Switch from archive libraries to partial linking

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Drop support for CONFIG_SKIP_RELOCATE_UBOOT

For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().

With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway. So don't keep this relict any
longer.

Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support. However, other recent changes led to a different
implementation (ELF relocation), where this no longer works. By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.
