I see that.
The problem is that the buildtool do not set variables defined in 
buildtool.cfg when using the buildclean, srcclean commands.
I need to fix the buildtool perl modules, so the variables will be set 
in any case.
To resolv the problem you can use the DIRNAME hack. Look for samba 
package for example:

SAMBA_DIR:=$(shell $(BT_TGZ_GETDIRNAME) $(SAMBA_SOURCE) 2>/dev/null )
ifeq ($(SAMBA_DIR),)
SAMBA_DIR:=$(shell cat DIRNAME)
endif

Then in .source:

.source:
     zcat $(SAMBA_SOURCE) | tar -xvf -
     echo $(SAMBA_DIR) > DIRNAME
     touch .source

So when the package is compiled it wrote the directory in the DIRNAME 
file, and when you use a clean command, as the SAMBA_DIR is empty it 
load is value from the DIRNAME file. It's ugly.
As soon as possible, i will try to make a fix.
