[PATCH] docs: bump minimal GNU Make version to 3.82

[PATCH] docs: bump minimal GNU Make version to 3.82

[Masahiro Yamada]

GNU Make 3.81 fails in CONFIG_RUST=y builds.

  rust/Makefile:105: *** multiple target patterns.  Stop.
  make[1]: *** [prepare] Error 2
  make: *** [__sub-make] Error 2

The error message looks weird, but the reason is that the 'private'
keyword is only supported since GNU Make 3.82.

GNU Make 3.81 is still able to build the kernel if CONFIG_RUST is
disabled, but it might be a good timing to bump the minimal GNU Make
version. Perhaps, I am the last person who was testing GNU Make 3.81.

GNU Make 3.81 was released in 2006, GNU Make 3.82 in 2010.

Sorry about that. Indeed, it was added in 3.82 [1,2]. Given GCC 5.1
(the current minimum) was released 5 years later, I guess it is OK to
increase it.
