[BusyBox] Conditionally compiling libbb/interface.c [PATCH]

[Shaun Jackman]

libbb/interface.c does not compile with newlib due to a number of
undefined structures, structure members, and preprocessor definitions.
libbb/interface.o could be conditionally compiled only if it's needed
by an applet, but the framework is not currently in busybox to
conditionally compile library objects. A simple solution is to wrap
interface.c in an indicative ifdef. I used SIOCGIFCONF for this
purpose. This is not the one and only solution though, so do speak up
if anyone has another suggestion.

Cheers,
Shaun

	* libbb/interface.c: Compile if SIOCGIFCONF is defined.
