# 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.

# liblua.so requires libm, so make sure it has an explicit dependency
# so that applications need not second-guess lua's dependencies.
