sanity.bbclass: check for validity of TMPDIR

From: Chen Qi <[email protected]>

Changes since V1:
1. Create the directory hierarchy for TMPDIR only if TMPDIR is valid
2. Handle ABI version change only if TMPDIR has been created.
3. If we had a valid TMPDIR for last build and this time the TMPDIR hasn't changed location, we don't check the validity for TMPDIR.

The following changes since commit ea92671d9823e3667d6ced7ac2af20f991da404d:

bitbake: cooker: replace "w" file opening mode with "a" mode (2013-11-12 17:01:37 +0000)

sanity.bbclass: check for validity of TMPDIR

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.
