[Buildroot] [git commit] package/libupnp18: add config option --enable-reuseaddr

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=09c5f205744dd5501f3ebc821a123133538e5540
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Enable the option to use SO_REUSEADDR on the built-in miniserver
socket to allow clean restarts [1].

This fixes a runtime issue with Gerbera and possible other programs
which does not allow a graceful restart otherwise.
