get errors when I compile pistachio-0.4

Hello.
Can pistachio-0.4 be compiled in Debian Linux.
I use gcc v4.x to compile it.
The step of my compiling as follow:
1. Run make BUILDDIR=<absolute path of nonexisting directory>
2. Chdir to the build directory!
3. Verify the settings in Makeconf.local!
4. Run make menuconfig or make xconfig!
5. Run make again!
But I think there are some errors in its Makefile, at least compiled in
Linux.
First, in kernel/src/platform/pc99/Makeconf, startup.S should be startup.s.
There is only startup.s in kernel/src/platform/pc99/.
Second, in kernel/Mk/Makeconf, it should be $(ECHO_MSG) $(subst
$(SRCDIR)/,,$<), but @$(ECHO_MSG) $(subst $(SRCDIR)/,,$<).
I have fixed the above two errors, but met another one.
This time, there is no message showing me. The output is as follow:

So what should I do now?
