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.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

Commit 7ebafb7ec1 introduced a mistake in the spi
init function call for those boards. This patch fixes this.

On the boards at91sam9260ek, at91sam9263ek and afed9260, the rstc register was
set to 0 after being set to 500 ms for the PHY reset.
Do backup the old reset length and restore it after the MACB initialisation.

AFEB9260 uses PA10, PA11 for ETX2 and ETX3.
Also, due to extarnal pull-up on IRQ line, Micrel PHY ID is 1 after reset sequence,
not 0.

AT91_BASE_EMAC is never used outside the board specific files,
so replace its usage by the board specific AT91xxx_BASE_EMAC.

AT91_ID_US0 / AT91_ID_US1 / AT91_ID_US2 were used but never defined.
Since they are never used outside the board specific files, they can
be replaced by the board specific AT91xxx_ID_US0 / AT91xxx_ID_US1 /
AT91xxx_ID_US2.

This patch provides support for AFEB9260 board, a product of
OpenSource hardware and software. Some commertial projects
are made with this design. A board is basically AT91SAM9260-EK
with some modifications and different peripherals and different
parts used. Main purpose of this project is to gain experience in
hardware design.
