Hi Team,

grub is failing while compiling.
Error Log is as follows:

My gcc version is 5.
I tried with installing updated gcc versions -7,-8, -9, but still facing
this issue.
Please let me know, how to resolve this.
Thanks in Advance

perhaps you are using an old distro to compile new yocto. This option
may not exist in gcc5, so perhaps you should write a patch to grub-efi
to remove using these options in configure.ac and conf/Makefile.common
and perhaps only apply this patch when building native or nativesdk
variant.
