GNU Make manual [1] clearly forbids a tab at the beginning of the
conditional directive line:
 "Extra spaces are allowed and ignored at the beginning of the
  conditional directive line, but a tab is not allowed."

This will not work for the next release of GNU Make, hence commit
82175d1f9430 ("kbuild: Replace tabs with spaces when followed by
conditionals") replaced the inappropriate tabs with 8 spaces.

However, the 8-space indentation cannot be visually distinguished.
Linus suggested 2-4 spaces for those nested if-statements. [2]

This commit redoes the replacement with 4 spaces.
