Adam Langley d062c8afba Probe for NEON support if getauxval is missing.
Android didn't have getauxval until Jelly Bean (4.1). This means that
BoringSSL running on older Androids won't be able to detect NEON
support. (This is moot for Chromium because Chromium calls
android_getCpuFeatures and sets the NEON flag itself, but other users of
BoringSSL on Android probably won't do that.)

This change mirrors a little of what upstream does and tries running a
NEON instruction with a handler for SIGILL installed.
