I've noticed that when I compile busybox on my laptop, it compiles more
slowly than one would expect, and although it's a (more-or-less)
multiprocessor system and I use -j5, make never seems to run more than
one job at a time.
I believe I have found the culprit: each time a file is compiled, gcc
runs about 5 times. This is because the $(check_gcc) macros and the
TARGET_ARCH macros are late binding.
The attached patch cuts the compilation time by 66%, from 1.5 minutes to
30 seconds. Your mileage may very. These statements have not been
evaluated by the FDA.

infrastructure, the compiler isn't smart enough to replace const static
int with the constant, and allocates space for each set of them,
bloating the executable something fierce. Oops.
So now, we #define ENABLE_XXX to 0 or 1 for each CONFIG_XXX (which
is still there so the 1000+ #ifdef/#ifndef tests don't have to be
replaced wholesale). Changed the test instance in networking/ifconfig.c
to use this.

Rob Landley, and others.
Currently CONFIG options are defined or undefined, so we chop out code with
#ifdefs, ala:
#ifdef CONFIG_THING
stuff();
#endif
This creates a new header file, bb_config.h, which sets the CONFIG entry to 1
or 0, and lets us do:
if(CONFIG_THING) stuff();
And let the compiler do dead code elimination to get rid of it. (Note: #ifdef
will still work because for the 1 case it's a static const int, not a #define.)

This fixes that, although the logic of both mv and cp is a bit tangled and
should probably be untangled.
