Add scan-build support to the build system.

When configured in Kconfig, just running "make"
calls scan-build as appropriate (however, it does not
check for the presence of scan-build)

The target directory for the scan-build report is configurable
and defaults to the scan-build default of /tmp/scan-build-$date-$num

abuild is adapted to properly run scanbuild when ran
with the -sb option.
