[oe] [PATCH][STABLE] Various SDK-related updates

[Tom Rini]

The following series brings stable up to date with dev, with respect to
SDK and Canadian SDK changes.  The only not directly SDK related change
is the bugfix to wireless-tools so that libiw can be used.  mwester said
I should pull the SlugOS-related fix in myself rather than wait for him
to update SlugOS stuff in stable.  These changes have been build-tested
for gcc 4.1.2/4.2.4/4.3.3 and at91sam9263ek qemuarm omap5912osk
beagleboard vortex86sx qemux86 mpc8313e-rdb with DISTRO=angstrom-2008.1
in both dev and stable with identical results.  These changes are also
in the trini/stable/2009/sdk-updates branch.
