[PATCH 6/7] signatures: exclude TOPDIR from signatures

[Felix Moessbauer <felix.moessbauer@siemens.com>]

The TOPDIR variable contains the absolute path to the build directory.
As the general build environment must not depend on the path
where the build is executed from, we can safely exclude the
variable from the signatures.

This finally make the build-dir relocatable and improves caching.
