Debian tends to enable all the features, while the embedded systems tend
to only turn on exactly what they need. Debian is trying to target a
generic platform and work for everything, while openwrt/lede/yocto tend
to aim at building for a specific target device.
OpenWRT uses musl for libc, not glibc, which has less features and
optimized for size rather than performance when there is a choice to
be made. Yocto lets you pick which libc you want to build with.
