Default CPPFLAGS on 64bit hosts

[Natanael Copa]

ncopa at nc ~/wrk/src/busybox/svn/busybox $ make
  SPLIT   include/autoconf.h -> include/config/*
  GEN     include/bbconfigopts.h
  HOSTCC  scripts/usage
  GEN     include/usage_compressed.h
  CC      applets/applets.o
applets/applets.c:1: error: -mpreferred-stack-boundary=2 is not between
4 and 12make[1]: *** [applets/applets.o] Error 1
make: *** [applets] Error 2

This was easy fixed by manually editing the Makefile.flags.

Why is CPPFLAGS used instead of CFLAGS?

btw...
One thing I noticed with the new build system: the parallell builds
(make -j5)  works! This reduces compile times alot, specially on
multicore systems.

Well done, Denis!
