[PATCH 14/20] tools build: Make the .cmd file more readable

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@xxxxxxxxxx>

Putting extra line between dependencies and cmd_* definition
to make it more readable.

Before:

  $ cat .builtin-top.o.cmd
  ...
  /home/jolsa/kernel/linux-perf/tools/include/linux/stringify.h \
  /home/jolsa/kernel/linux-perf/tools/include/linux/time64.h
  cmd_builtin-top.o := gcc -Wp,-MD,./.builtin-top.o.d -Wp,-MT,builtin-...
  ...

After:

  $ cat .builtin-top.o.cmd
  ...
  /home/jolsa/kernel/linux-perf/tools/include/linux/stringify.h \
  /home/jolsa/kernel/linux-perf/tools/include/linux/time64.h

  cmd_builtin-top.o := gcc -Wp,-MD,./.builtin-top.o.d -Wp,-MT,builtin-...
  ...
