Subject: [PATCH] linux-user: fix openat
When running openat using qemu-arm, we stumbled over invalid permissions
on the created files. The reason for this is that the mode parameter gets
treates as an O_... flag, which it isn't - it's a permission bitmask.
This patch removes the needless translation of the mode parameter,
rendering permission passing of openat() to work with linux-user.
