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.
