tests: support building Linux tests in-tree

Previously, you had to manually invoke gcc to build the tests.  Now,
anytime you make tests, you'll also get the Linux version.  The tests
that are built for both OSes are specified manually in the Makefile.

This will also build any Linux modules in tests/linux/modules/.  You'll
need to provide LINUX_KDIR, e.g. in your Makelocal.  This is for tests
that need kernel support, such as the upcoming lock_test mcs-kernel mode.

You can also build these programs directly by cd-ing into tests/linux
and running Make.  This won't use any of the top-level Makefile
features (including Makelocal settings).  It's convenient if you don't
want to build Akaros (toolchain recompile, etc.).

Either way, the test binaries will appear in tests/linux/obj/.  The
top-level obj/ is just for Akaros's build output.
