# Overriding __MAKE_CONF makes sure that we don't re-parse
# /etc/make.conf during do-build, which would jeopardize the build
# if, for instance, the user set CFLAGS=mumble
# NOTE: /etc/make.conf is read BEFORE Makefile, so we already
# have its settings when we get here.

# using the "bsd" target rather than "freebsd" saves patching out the
# assumption of using base libedit in order to make it configurable. "bsd"
# is "generic" plus the POSIX and DLOPEN options, plus -Wl,-E at link time;
# it doesn't set CC either, which makes it easier for us to control that too.
