Changing BB_NUMBER_THREADS between successive builds causes a "basehash value changed" error. Fix by using vardepsexclude since the parallelism is supposed to not modify the build result.
Fixes: ERROR: When reparsing .../meta-ti/recipes-ti/ipc/ti-ipc-rtos_git.bb.do_configure, the basehash value changed from 63897a188012cedde03f756b5dbbfa70 to 13b80bf4f4327c367bd201eb4aa32ad7. The metadata is not deterministic and this needs to be fixed.
