scons: Control caching via new SCONS_CACHE_DIR environment variable.
This serves several purposes: - disable caching in situations were is it useless or undesired - share caches among all trees - simplify purging the cache (when it's a single location) - move the cache out of the tree, since that slows downs IDEs considerably To retain previous behavior just define do export SCONS_CACHE_DIR=$PWD/build/cache before invoking scons.
