package/softether/0007-uclibc-ai-addrconfig.patch

   1 Only enable getifaddrs support when available
   2
   3 On uClibc, the ifaddrs.h support is optional. While the default
   4 Buildroot uClibc configuration has it enabled, some external
   5 toolchains may not. Therefore this patch detects that and adjusts
   6 softether usage of ifaddrs accordingly.
   7
   8 Based on an initial patch from Bernd Kuhls.
