Forced commit to note that the previous commit to this file included the
following MFC as well:

MFC 278251:

Honor the following flags for items that can be conditionalized out of the
build/install without disrupting other dependent services (see r278249, et
al):

- MK_LOCATE
- MK_MAN
- MK_NLS
- MK_OPENSSL
- MK_PKGBOOTSTRAP
- MK_SENDMAIL

Additional flags need to be handled in etc/Makefile, but it requires
refactoring the relevant scripts in etc/rc.d/*
