  Ok,  World  build  time was reduced from 1:27 to just 0:27. building
 clang and binutils twice takes one hour (!!!!!)? or 2/3 of buildworld
 time!.

  But, of course, headers should be equivalent to ones in sources.
 Also,  disabled binutils lead to inability to install worils (install
 -s doesn't work).

  Returning binutils to build (to allow `install -s' works) yelds only
 1 or 2 minutes, Ok.

  It  is  very sad, that external compiler cannot be used with "fresh"
 sources (when headers are different). We need some solution for this,
 for  sure!  When  compilers are identical (same clang revision), but
 sources has updated headers. It does proper trick with libraries, but
 not with headers!

  Also, it should be possible to use system strip in such case.
