I'd be fine with that if it's your preferred solution. In general I
like to avoid ifdefs on specific targets, otherwise the source
eventually ends up looking like #if !SPARC && !CRAY &&
(POSSIBLY_A_GAMEBOY || OR_MAYBE_A_CRUSOE). It can only get worse.

There's very little of busybox that actually requires Linux. With few
changes it will run well on BSD or a non-Linux embedded target. The
most significant step is simply avoiding using include linux/* and
asm/*, which by simple definition cannot be used on anything but
Linux. I have to objections to Linux specific utilities that can be
omitted from the .config file. However source files in libbb that are
always compiled should play nice with other systems.

We could add a CONFIG_FEATURE_LINUX, which is set by default. It's
primary purpose would be to #ifdef around #include <linux/*> and
#include <asm/*> statements that cause the build to stop dead in its
tracks for non-Linux systems.
