Agreed.  I haven't been able to come up with a way to convince make to
adjust the destination path according to the source path.  Given this
subset of rules from /usr/src/etc/sendmail/Makefile:

.SUFFIXES:	.mc .cf

.mc.cf:		${M4FILES}
	${RM} ${.TARGET}
	(cd ${.CURDIR} && \
	    ${M4} -D_CF_DIR_=${CFDIR}/ ${SENDMAIL_M4_FLAGS} \
		${CFDIR}/m4/cf.m4 ${@:R}.mc) > ${.TARGET}
	${CHMOD} ${ROMODE} ${.TARGET}

SENDMAIL_MC=	/etc/mail/foo.mc
SENDMAIL_ADDITIONAL_MC=	/usr/local/etc/foo.mc

INSTALL_CF=	${SENDMAIL_MC:R}.cf
SENDMAIL_ADDITIONAL_CF=	${SENDMAIL_ADDITIONAL_MC:S/.mc$/.cf/g}

all:	${INSTALL_CF} ${SENDMAIL_ADDITIONAL_CF}

Currently, /etc/mail/foo.cf and /usr/local/etc/foo.cf will be built.
I'd prefer /usr/obj/usr/src/etc/sendmail/etc/mail/foo.cf and
/usr/obj/usr/src/etc/sendmail/usr/local/etc/foo.cf be created during
buildworld and installed to /etc/mail/ and /usr/local/etc/ respectively
during installworld.  (See /usr/src/etc/sendmail/Makefile for install
rules).

Any Makefile gurus out there who can help?
