Android now requires PIE executables

[DanAlbert]

Android's linker no longer supports non-PIE executables: https://android-review.googlesource.com/#/c/93842/

# Rust hello world on ToT AOSP:
$ adb shell /data/local/tmp/hello
error: only position independent executables (PIE) are supported.

this issue should be closed, as there is a commit in that fixes it and says "closes". I'm not sure why it's not.

except maybe not, because it still happens on latest rust. what gives?

[lahwran]

workaround, since it still seems to be broken: pass -C link-args=-pie to rustc. (makes it work on my vanilla, admittedly rooted, hammerhead/nex5.)
