[CFT][patch] buildsys touch-up and standalone applets

[Bernhard Fischer]

Hi,

The attached patch
- fixes parallel builds (make -j) to work again.
- uses less resources for the buildsystem itself.
- adds a (very) rough proposal for building standalone applets.
  See "Build options" Standalone applets.
  I changed coreutils/true and editors/* so you can try these as
  standalone.

I tested it with make-3.81beta4 and tried my best to workaround bugs in
make-3.80.

Please test and let me know what you think.

PS: For this quick approach, i avoided to create a standalone.c helper
file, this can be changed easily if this is preferred.
PPS: I didn't fix vi for standalone compilation.
