Thomas Petazzoni d9cf0a76db softether: add patch to fix build on uClibc toolchain without ifaddr support
This commit adds a patch to softether to make sure it doesn't use the
ifaddrs functions when they are not provided by the C library, which
can be the case with certain external uClibc toolchains.

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.
