--prefix="/usr/" \
--sysconfdir="/etc" \
--enable-nfqueue \
--localstatedir="/var" \
--enable-nfqueue \
--enable-debug \
--enable-lua \
--enable-geoip \
--disable-gccmarch-native \
--with-suricata-update \
--host=$(RUSTC_TARGET_ARCH)
these are my arg calls for ./configure (after autogen.sh). RUSTC_TARGET_ARCH, in my case, is mips64-unknown-linux-muslabi64
