GNU Make removes downloaded zip files for no apparent reason

I have this makefile tha sthould download and build openssh (along with
other things):
ROOT_DIR=$(PWD)
DATA_DIR=$(ROOT_DIR)/data
SOURCES_DIR=$(ROOT_DIR)/sources
RESOURCES_DIR=$(ROOT_DIR)/resources
DRAFTS_DIR=$(ROOT_DIR)/drafts
$(SOURCES_DIR):
mkdir $(SOURCES_DIR)
$(RESOURCES_DIR):
mkdir $(RESOURCES_DIR)
$(DRAFTS_DIR):
mkdir $(DRAFTS_DIR)
openssh-tar-url="ftp://ftp.cc.uoc.gr/mirrors/OpenBSD/OpenSSH/portable/openssh-6.2p2.tar.gz"
TAR_PROJECTS += openssh
openssh:
echo "Building $@"
openssh-clean: openssh-archive-clean
.SECONDEXPANSION :
$(TAR_PROJECTS) : $(SOURCES_DIR) $(SOURCES_DIR)/$$@-archive
$(DRAFTS_DIR)/%.tar.gz: $(DRAFTS_DIR)
echo "Pulling $*."
wget $($*-tar-url) -O $(DRAFTS_DIR)/$*.tar.gz
.SECONDEXPANSION :
$(SOURCES_DIR)/%-archive : | $(DRAFTS_DIR)/$$*.tar.gz
mkdir $@
cd $@ && tar xvzf $(DRAFTS_DIR)/$*.tar.gz
%-archive-clean:
rm -rf $(SOURCES_DIR)/$*-archive $(DRAFTS_DIR)/$*.tar.gz
When i run make openssh it runs correctly but at the end it removes the
archive it downloaded. This is very strange to me:
$ make openssh --just-print
echo "Pulling openssh."
wget
"ftp://ftp.cc.uoc.gr/mirrors/OpenBSD/OpenSSH/portable/openssh-6.2p2.tar.gz"
-O
/home/fakedrake/Projects/ThinkSilicon/xilinx-zynq-bootstrap/drafts/openssh.tar.gz
mkdir
/home/fakedrake/Projects/ThinkSilicon/xilinx-zynq-bootstrap/sources/openssh-archive
cd
/home/fakedrake/Projects/ThinkSilicon/xilinx-zynq-bootstrap/sources/openssh-archive
&& tar xvzf
/home/fakedrake/Projects/ThinkSilicon/xilinx-zynq-bootstrap/drafts/openssh.tar.gz
echo "Building openssh"
rm
/home/fakedrake/Projects/ThinkSilicon/xilinx-zynq-bootstrap/drafts/openssh.tar.gz
