So this would introduce unrelated changes, but it seems that we don't
have much trailing whitespaces in progs codebase:

  $ git grep '\s\+$'
  btrfs-fragments.c:
  btrfs-fragments.c:                              black = gdImageColorAllocate(im, 0, 0, 0);  
  crypto/crc32c.c:/* 
  crypto/crc32c.c: * 
  crypto/crc32c.c: * Software Foundation; either version 2 of the License, or (at your option) 
  crypto/crc32c.c: * Steps through buffer one byte at at time, calculates reflected 
  crypto/crc32c.c: * Steps through buffer one byte at at time, calculates reflected 
  kernel-lib/radix-tree.h: * 
  kernel-lib/radix-tree.h: * 
  kernel-lib/rbtree.c:            node = node->rb_right; 
  kernel-lib/rbtree.c:            node = node->rb_left; 
  kernel-lib/rbtree.h:  

filtering only the sources. So let's keep it in the config.
