Auto merge of #3180 - jsha:print-rustc-error-output, r=JohnTitor0.2.141
build.rs: print rustc stderr if exit status != 0
I was trying to run benchmarks locally with rustc-perf and found that many of them failed to build with a message from libc's build.rs "Failed to get rustc version." I made this change locally to help debug, and I think it would be generally useful. In my case it quickly revealed that rustc was failing to find libLLVM and so `rustc --version` was emitting nothing on stdout.
I think this may have been part of what was intended with #3000 and might help debug https://github.com/rust-lang/crater/issues/663.
