Why not use dhcpcd?
It's a lot heavier than udhcpcd, but comes with link detection and
IPV4LL (aka zeroconf, aka link local address) management and a host of
other features.

It supports NOMMU systems and comes in at around 65k on i386 built -O2
not stripped, so I imagine it gets much smaller with -Os and stripped.
