Subject: [PATCH] kbuild: Replace tabs with spaces when followed by
conditionals
This is needed for the future (post make-4.4.1) versions of gnu make.
Starting from https://git.savannah.gnu.org/cgit/make.git/commit/?id=07fcee35f058a876447c8a021f9eb1943f902534
gnu make won't allow conditionals to follow recipe prefix.
For example there is a tab followed by ifeq on line 324 in the root Makefile.
With the new make this conditional causes the following
$ make cpu.o
/home/dgoncharov/src/linux-kbuild/Makefile:2063: *** missing 'endif'. Stop.
make: *** [Makefile:240: __sub-make] Error 2
This patch replaces tabs followed by conditionals with 8 spaces.
See https://savannah.gnu.org/bugs/?64185 and
https://savannah.gnu.org/bugs/?64259 for details.
