We thought Google's ABI for arvm7 required neon, but it is currently optional, perhaps because there is a significant population of Tegra 2 devices still in use. This turns off neon code generation outside #[target-feature] blocks just like we do on armv7-unknown-linux-gnu, but unlike most other armv7 targets. LLVM defaults to +neon for this target, so an explicit disable is necessary. See https://developer.android.com/ndk/guides/abis.html#v7a for instruction set extension requirements. Closes rust-lang#38402.
Hopefully these references will be stable and provide guidance when requirements change in the future.
This tiny patch merely applies @bluss's suggestion for how to get a more informative error message when the feature check can't open a file, a matter that had briefly annoyed the present author, leading to the filing of rust-lang#38417.
The current beta that rustc is bootstrapping from contains a bug in Cargo that erroneously links to OpenSSL in /usr/local, but this is fixed in the most recent 1.14 beta, so let's use that.
This not only avoids the small – and unnecessary – constant overhead for each compiler invocation, but also helps somewhat by only having “correct” rustc processes to look for in `/proc/`. This also makes the wrapper behave effectively as a regular exec wrapper its intended to be.

Update beta bootstrap compiler The current beta that rustc is bootstrapping from contains a bug in Cargo that erroneously links to OpenSSL in /usr/local, but this is fixed in the most recent 1.14 beta, so let's use that.
stage0.txt: typo fix
Use exec for the wrapper on UNIXes This not only avoids the small – and unnecessary – constant overhead for each compiler invocation, but also helps somewhat by only having “correct” rustc processes to look for in `/proc/`. This also makes the wrapper behave effectively as a regular exec wrapper its intended to be. I also took liberty to change the fallback error code from `1` to `0xfe` (now only relevant on windows) so that when people complain about “compiler exited with code 254”, its obvious where the issue lies (wrapper losing the exit code somehow). r? @alexcrichton
