Sebastien Carlier 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.

Memory Map from CPU point of view:

    Start	 Size	Access to
    -----------------------------------------------------
    0x00000000	 64MB	SDRAM DIMM
    0xFF000000	  4MB	On Board FLASH
    0xFFF00000	512K	On Board FLASH or SRAM (Configured by jumper)
    0xFFE00000	  8K	EEPROM
    0xFFE80000	  8Bit	LED
    0xFFF80000	  8Bit	UART


Setting the board Jumpers & Switches:

   In order to get the board running with the default configuration the
   jumpers need to be set as follows:

  General Jumpers:
    ____________________________________________
   |   Jumpers	 |   Jumpers	|    Jumpers	|
   |-------------|--------------|---------------|
   |JP1	    1-2	 | JP14	   1-2	| JP27	  1-2	|
   |JP5	    Open | JP15	   1-2	| JP28	  2-3	|
   |JP8	    1-2	 | JP16	   1-2	| JP33	  Open	|
   |JP9	    1-2	 | JP17	   1-2	| JP37	  Close |
   |JP10    1-2	 | JP18	   1-2	|		|
   |JP11    2-3	 | JP19	   1-2	|		|
   |JP12    1-2	 | JP20	   1-2	|		|
   |JP13    1-2	 | JP25	   Open |		|
   |_____________|______________|_______________|

  Bus speed Jumpers:
