Building with a newer ld results in two warnings:

    binutils-2.39/bin/ld: warning: defaultenv/defaultenv-2-reboot-mode.bbenv.gz.o:
    missing .note.GNU-stack section implies executable stack
    binutils-2.39/bin/ld: NOTE: This behaviour is deprecated and will be removed
    in a future version of the linker
    binutils-2.39/bin/ld: warning: barebox has a LOAD segment with RWX permissions

This is already fixed for the non-sandbox platform with a4b49c69c3ad
("Kbuild: link with -z noexecstack and --no-warn-rwx-segments"), but
sandbox has its own cmd_barebox__, so add the equivalent to the sandbox
Makefile as well.
