4Subject: [PATCH] grub module explicitly keeps symbole .module_license
5
6While using oe-core toolchain to strip grub module 'all_video.mod',
7it stripped symbol table:
8
9---------------
10root@localhost:~# objdump -t all_video.mod
11
12all_video.mod:     file format elf64-x86-64
13
14SYMBOL TABLE:
15no symbols
16--------------
17
18It caused grub to load module all_video failed.
19--------------
20grub> insmod all_video
21error: no symbol table.
22--------------
23
24Tweak strip option to keep symbol .module_license could workaround
25the issue.
26--------------
27root@localhost:~# objdump -t all_video.mod
