How run make file in rpi4

Question

I have built on ubuntu host the kernel/rootfs for rpi4 model b 64-bit with latest buildroot and using crosstoolng aarch64-rpi4-linux-gnu and raspberry pi os as source . How can I run a make file in the rpi? I don't think buildroot has menuconfig option for opkg or apt-get to install make

Thanks

Didn't find it in menuconfig, but in buildroot's built config dir i could edit raspberrypi4_64_defconfig:

BR2_PACKAGE_OPKG=y
# BR2_PACKAGE_OPKG_GPG_SIGN is not set
BR2_PACKAGE_OPKG_UTILS=y
# BR2_PACKAGE_HOST_OPKG_UTILS is not set
