Subject: [PATCH] grub module explicitly keeps symbole .module_license
While using oe-core toolchain to strip grub module 'all_video.mod',
it stripped symbol table:
---------------
root@localhost:~# objdump -t all_video.mod
all_video.mod: file format elf64-x86-64
SYMBOL TABLE:
no symbols
--------------
It caused grub to load module all_video failed.
--------------
grub> insmod all_video
error: no symbol table.
--------------
Tweak strip option to keep symbol .module_license could workaround
the issue.
--------------
root@localhost:~# objdump -t all_video.mod
all_video.mod: file format elf64-x86-64
SYMBOL TABLE:
