$1 - generic step name (e.g., CC, LINK, etc);

$2 - optional "flavor" specifier; if provided, will be emitted as [flavor];

$4 - optional extra arg, emitted as-is, if provided.

Get Clang's default includes on this system, as opposed to those seen by

'--target=bpf'. This fixes "missing" files on some architectures/distros,

such as asm/byteorder.h, asm/socket.h, asm/sockios.h, sys/cdefs.h etc.

Use '-idirafter': Don't interfere with include mechanics except where the

build would have failed anyways.
