20090310-3-scanbuild: 

Add support for clang's scan-build utility to abuild. scan-build wraps
the compiler and runs its own compiler on the same sources to do some
static analysis on them. It adds an option "-sb" or "--scan-build" that
creates a coreboot-builds/$target-scanbuild directory for every $target,
containing the output of scan-build, which is a HTML documentation on
its results.
Be aware, that scanbuild significantly increases build time: A board
that takes 6-7 seconds normally requires 60 seconds with that option
enabled on my test system.
The patch also moves the stack-protector option down a bit, so it
applies to crosscompiled targets, too (which overwrote the compiler
settings before)
