When compiling with LTO, the compiler fails with an error saying that
`crc_table` causes a section type conflict with `efi_var_buf`.
This is because both are declared to be in the same section (via macro
`__efi_runtime_data`), but one is const while the other is not.
Make this variable non-const in order to fix this.
This does not look right, the crc32 array is constant.
Maybe what you want to do instead if create some __efi_constant_data
section ?
Yes, this was the easier solution, and maybe is not ideal.
I thought it would not be much of a problem since this array can be
nonconstant (generated after boot) if CONFIG_DYNAMIC_CRC_TABLE is
enabled.
Anyway I don't much understand the EFI code so I wanted to poke into it
as little as possible.
Isn't the compiler capable of better optimization on constant stuff ?
That's pretty much what prompted my suggestion to add separate section.
