From 7f41db8f9ac4c5c50b32c6e2315aa1e6aa72afb3 Mon Sep 17 00:00:00 2001 From: Martin Bark Date: Mon, 15 Feb 2016 13:00:06 +0000 Subject: [PATCH] package/iputils: patch ping to link against libm ping fails to compile with uClibc based toolchains with the error undefined reference to `__finite' Add a patch to link ping against libm to resolve the math library function finite(). Note, this error is not seen with glibc based toolchains because finite seems to be resolved in both libm and libc.
