[Buildroot] [git commit] grub2: fix build with BR2_STRIP_none

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=fc174b7057495ebb31393ae27f3ceeefdc490022
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

grub2 assumes the strip command will generate output and the output should
always be stripped - so, just use the $(TARGET_CROSS)strip to make sure that
the build succeeds regardless of the buildroot strip configuration.
