Michael Chang 7ea474c688 cpio: Disable gcc9 -Waddress-of-packed-member
Disable the -Wadress-of-packaed-member diagnostic for the
grub_cpio_find_file function since the result is found to be false
postive. Any pointers to member of the 'struct head hd' is aligned even
if the structure is packed without paddings.

This is GRUB 2, the second version of the GRand Unified Bootloader.
GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more
robust, more powerful, and more portable.

See the file NEWS for a description of recent changes to GRUB 2.

See the file INSTALL for instructions on how to build and install the
GRUB 2 data and program files.

Please visit the official web page of GRUB 2, for more information.
The URL is <http://www.gnu.org/software/grub/grub.html>.

More extensive documentation is available in the Info manual,
accessible using 'info grub' after building and installing GRUB 2.

There are a number of important user-visible differences from the
first version of GRUB, now known as GRUB Legacy. For a summary, please
