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.

Moved initialization of AVR32 Ethernet controllers to board_eth_init() Renamed initialization functions for atngw100 and atstk1000.
