Add support for a saving build objects in a separate directory. Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

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. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

disk/part.c: Make features optional If we don't want to build support for any partition types we can now add #undef CONFIG_PARTITIONS in a board config file to keep this from being compiled in. Otherwise boards assume this is compiled in by default Signed-off-by: Matthew McClintock <msm@freescale.com>

disk: convert part_* files to COBJ-$(CONFIG_XXX) style Move the CONFIG_XXX out of the part_XXX.c file and into Makefile to avoid pointless compiles. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Build: split COBJS value into multiple lines This change is in preparation for condtitionial compile support in the build system. By spliting them all into seperate lines now, subsequent patches that change 'COBJS-y += ' into 'COBJS-$(CONFIG_<blah>) += ' will be less invasive and easier to review Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
