The top level Makefile does not do any recursion into subdirs when
cleaning, so these clean/distclean targets in random arch/board dirs
never get used. Punt them all.
MAKEALL didn't report any errors related to this that I could see.

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.

Recently the YAFFS filesystem support has been added to U-boot.
However, just enabling CONFIG_YAFFS2 is not enough to get it working.
ymount will generate an exception (when dereferencing mtd->readoob()), because
the genericDevice is a null pointer. Further, a lot of logging is produced
while using YAFFS fs, so logging should also be disabled.
Both issues are solved by this patch.
With this patch and CONFIG_YAFFS2 enabled, I get a readable filesystem
in U-boot, as well as in Linux.
Tested on a Atmel AT91SAM9261EK board.
