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.

f6a7a2e888 ati_radeon: Support PCI virtual not eq bus mapping.
Use pci_bus_to_virt() to convert the bus address from the BARs to
virtual address' to eliminate the direct mapping requirement.

Rename variables to better match usage (_phys -> _bus or no-suffix)

This fixes the mpc8572ds CONFIG_PHYS_64BIT mode failure:
"videoboot: Video ROM failed to map!"

Tested on mpc8572ds with and without CONFIG_PHYS_64BIT.

285870f753 Leave x86emu op code tables in default section
Forcing the tables into got2 caused extra relocation when using -mrelocatable.
This patch requires any board defining CONFIG_BIOSEMU to use -mrelocatable.

9aef738885 unify HOST_CFLAGS and HOSTCFLAGS
The top build system sets up HOSTCFLAGS a bit and exports it, but other
places use HOST_CFLAGS instead.  Unify the two as HOSTCFLAGS so that the
values stay in sync.

The function parse_line() in common/main.c was exposed globally by commit

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.
