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.

This patch fixes an error when running MAKEALL for ARM9.
On OS X /bin/sh uses builtin echo which does not utilise '-n' switch.
GNU manual for builtins recomend to use here-document style to solve
this portability issue.
This patch removes the usage of 'echo -n' and replace by here-document
style or a oneline echo command.

pci_eth_init() is already conditional to CONFIG_PCI so not every caller
needs to have conditionals.
This is the only place in the current code base where such a check is
still at the calling site.

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.
This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

All in-tree boards that use this controller have CONFIG_NET_MULTI
added
Also:
- changed CONFIG_DRIVER_SMC91111 to CONFIG_SMC91111
- cleaned up line lengths
- modified all boards that override weak function in this driver
- modified all eeprom standalone apps to work with new driver
- updated blackfin standalone EEPROM app after testing

The board/armltd/integrator/split_by_variant.sh script used to print
"Configuring for integrator*p board..." no matter which board name
was being compiled. This made it difficult to match MAKEALL output to
board names. This patch fixes this.
