Background:
drbd-kernel compiles from source directory drbd.
drbd compiles from source directory drbd-tools.
In one cleanup path the build tools incorrectly assume
package name = source directory name.
As a result "build-pkgs --clean drbd" was incorrectly deleting
a temporary directory named 'drbd' that was in fact the temporary
directory for package drbd-kernel.
For incremental parallel builds this can lead to build failures
if drbd is cleaned in paraller with drbd-kernel being built.
