Makefile: export a few variables to help support scripts
Support scripts (in support/) may need to parse the .config file, so give them an easy access to it, by exporting BUILDROOT_CONFIG with the fully- qualified path to .config. Also, post-build scripts may need to reference a few locations, so export those, too. Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR is used internally, while O is used on the command line, which makes it a bit ambiguous to know which to use. As users use O= on the command line, they will probably tend to use that in their post-build scripts. Update doc accordingly. [Peter: fixed typo] Signed-off-by: "Yann E.
