[OE-core] [PATCH 1/2] scons.bbclass: Force rebuild if necessary

[Burton, Ross]

This make me look at scons a bit closer, somewhat in shock that it
doesn't have a native way of doing out of tree builds.  Apparently
abusing the repository argument will sometimes work for out of tree
(so you could just put B=$WORKDIR/build and add B to [cleandirs]) but
abusing sounds like 'doesn't always work' to me.

I then discovered that the one recipe in oe-core that uses scons
doesn't in fact use the class, and switching to it breaks because
there's no standard way of passing install paths (serf tries to
install to /usr on the host).

So how is your experience with the scons class? Is it actually useful?
