When linking with LTO, the compiler complains about type mismatch of variables `__efi_runtime_start`, `__efi_runtime_stop`, `__efi_runtime_rel_start` and `__efi_runtime_rel_stop`:
include/efi_loader.h:218:21: warning: type of ‘__efi_runtime_start’ does not match original declaration [-Wlto-type-mismatch] 218 | extern unsigned int __efi_runtime_start, __efi_runtime_stop; | ^ arch/sandbox/lib/sections.c:7:6: note: ‘__efi_runtime_start’ was previously declared here 7 | char __efi_runtime_start[0] __attribute__((section(".__efi_run | ^
Change the type to char[] in include/efi_loader.h.
