b8eee4354f Build arch/$ARCH/lib/bootm.o depending on CONFIG_CMD_BOOTM
MAKEALL is fine for ppc4xx and mpc85xx.
Run checks were done on our controlcenterd hardware.

2281ba5172 microblaze: Add muldi3.c which contains routines for _muldi3
Referenced arch/blackfin/lib/muldi3.c and the linux kernel.
Resolves issue seen when building u-boot for HW_MUL=0;

PLATFORM_CPPFLAGS += -mxl-soft-mul
PLATFORM_CPPFLAGS += -mno-xl-multiply-high

which resulted in error while linking to libgcc.a without mul hw (bs / m);

libgcc.a(_muldi3.o): In function `__muldi3':
.... src/gcc-4.6.2/libgcc/libgcc2.c:550: undefined reference to `_GLOBAL_OFFSET_TABLE_'

This link failure would not occur if we used gcc instead of ld directly, as
gcc will correctly use the crt's to resolve this link.

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.

ea0364f1bb Move lib_$ARCH directories to arch/$ARCH/lib
Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk

This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.
