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 OMAP3 cpu directory contains a syslib file with some utilities
that can be shared by all targets using arm cortexa8 processors,
not only OMAP.

and OMAP4
The functions in syslib.c can be shared, so this patch moves it from
cpu/omap3 to cpu/omap-common

This patch adds minimum support for OMAP4. Code which can be shared
between OMAP3 and OMAP4 is placed in arch/arm/cpu/armv7/omap-common
