and then

ASTLIBDIR=$(INSTALL_PREFIX)/usr/lib/asterisk
ASTVARLIBDIR=$(INSTALL_PREFIX)/var/lib/asterisk
ASTETCDIR=$(INSTALL_PREFIX)/etc/asterisk
ASTSPOOLDIR=$(INSTALL_PREFIX)/var/spool/asterisk
ASTLOGDIR=$(INSTALL_PREFIX)/var/log/asterisk
ASTHEADERDIR=$(INSTALL_PREFIX)/usr/include/asterisk
ASTCONFPATH=$(ASTETCDIR)/asterisk.conf
ASTBINDIR=$(INSTALL_PREFIX)/usr/bin
ASTSBINDIR=$(INSTALL_PREFIX)/usr/sbin
ASTVARRUNDIR=$(INSTALL_PREFIX)/var/run
ASTMANDIR=$(INSTALL_PREFIX)/usr/share/man

produces wonderful stuff like

ASTLIBDIR=/usr/local/usr/lib/asterisk
