IP Filter 4.0beta5, Makefiles

Buiding packages under Solaris did not work. Reason:
The make parameter passing for make install-... in Makefile and the
32-bit-only package building in SunOS5/Makefile are broken (haven't checked
non-SunOS5 architectures). Here are patches (in short diff form):
*** Makefile:
326c326
< (cd SunOS4; $(MAKE) "CPU=$(CPU) TOP=.." install)
---
> (cd SunOS4; $(MAKE) "CPU=$(CPU)" "TOP=.." install)
329c329
< (cd SunOS5; $(MAKE) "CPU=$(CPU) TOP=.." install)
---
> (cd SunOS5; $(MAKE) "CPU=$(CPU)" "TOP=.." install)
332c332
< (cd HPUX; $(MAKE) "CPU=$(CPU) TOP=.." "BITS=`getconf KERNEL_BITS`" install)
---
> (cd HPUX; $(MAKE) "CPU=$(CPU)" "TOP=.." "BITS=`getconf KERNEL_BITS`" install)
335c335
< (cd IRIX; smake install "CPU=$(CPU) TOP=.." $(DEST) $(MFLAGS))
---
> (cd IRIX; smake install "CPU=$(CPU)" "TOP=.." $(DEST) $(MFLAGS))

*** SunOS5/Makefile:

< ipf.pkg.bin; TOP=$(TOP)) \
