From: Chen Qi <Qi.Chen@windriver.com>

TMPDIR must be an absolute path, otherwise, the build will fail.
Special characters in TMPDIR will also cause build failures.

This patch enables checking for the validity of TMPDIR.

The logic in sanity.bbclass has also been changed a little bit. For now,
we only create the directory hierarch for TMPDIR if TMPDIR is valid. And
also, we only handle ABI version change only if the TMPDIR directory hierarchy
has been created.
