androidndk: fix make-standalone-toolchain.sh helper script

The script does a copy of a toolchain and then rearranges files a bit.
The problem is that these files have the same permissions (read-only)
as installed ones. The patch fixes the problem by changing permissions
of the copy before doing anything else.

BOSSA: Try to fix a nondeterministic build failure.

There's a Make rule to generate .cpp from .asm but the .cpp is included
in the source. Presumably the timestamps of these two files in the tmp
dir are different when Hydra is building, but not on my system. This
causes Make to try to rebuild .cpp, but the tools needed for that are missing.

iproute: Fix regressions introduced in 3.16.0

3.16.0 introduced a regression where vlan and veth devices could not be
created due to a check in the code for existing devices. This applies
the upstream patch which fixes the issue.

Additionally, this corrects the nixos network-interfaces task which now
needs to specify the name parameter when adding links.
