Subject: efi_loader: suppress executable stack warning
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a8d52f9a9b7be90decc6eabae39ec360bda5cd15;p=u-boot.git

efi_loader: suppress executable stack warning

When linking EFI binaries the linker emits:

    ld.bfd: warning: lib/efi_loader/efi_crt0.o:
    missing .note.GNU-stack section implies executable stack

Suppress the warning.
