Subject: umdns: fix unused error
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ab7a39a5b5a0ff74601dd4e82145ca554c1e2ac6;p=oweals%2Fmdnsd.git

umdns: fix unused error

Umdns does not compile on target-arm_cortex-a15+neon-vfpv4_musl_eabi.
Add the ttl variable to debug output to supress unused warning that
leads to an error.
