+Only enable getifaddrs support when available
+
+On uClibc, the ifaddrs.h support is optional. While the default
+Buildroot uClibc configuration has it enabled, some external
+toolchains may not. Therefore this patch detects that and adjusts
+softether usage of ifaddrs accordingly.
+
+Based on an initial patch from Bernd Kuhls.
