Add atsectl, a simple utility to read and update MAC addresses stored in

the default flash location on Altera DE4 boards.  Typically used once
when setting up a board so leaving in tools rather than inflicting on
all users.

To build with world add LOCAL_DIRS=tools/tools/atsectl to the make
command line.

Stop conflating WITHOUT_CLANG with WITHOUT_CLANG_IS_CC.  This allows
bootstrapping a copy of clang without building clang for the base system

which is useful for nanobsd and similar setups.  It's still probably
wrong to conflate what is installed as /usr/bin/cc with the selection
of a bootstrap compiler under WITH*_CLANG_IS_CC, but that's for another
day.
