Masahiro Yamada 44929bface kbuild: remove GCC's default -Wpacked-bitfield-compat flag 
Commit 4a5838ad9d ("kbuild: Add extra gcc checks") added the
-Wpacked-bitfield-compat flag, but there is no need to add it
explicitly.

GCC manual says:
  "This warning is enabled by default. Use -Wno-packed-bitfield-compat
   to disable this warning."

The test code in the manual:

  struct foo
  {
    char a:4;
    char b:8;
  } __attribute__ ((packed));

... emits "note: offset of packed bit-field ‘b’ has changed in GCC 4.4"
without W=3.

Let's remove it, as it is a default with GCC.

Clang does not support this flag, so its removal will not affect Clang
builds.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
