2956532625 Move DECLARE_GLOBAL_DATA_PTR to file scope
It can be optimised out by the compiler otherwise resulting
in obscure errors like a board not booting.

This has been documented in README since 2006 when these were
first fixed up for GCC 4.x.

6d8962e814 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.

8a3f6bb6fb OMAP3: Add support for the IGEP v2 board.
The IGEP v2 board is a low-cost, fan-less and industrial temperature
range single board computer that unleashes laptop-like performance and
expandability without the bulk, expense, or noise of typical desktop
machines. Its architecture shares much in common with other OMAP3 boards.
