Flush printf after every output, so we can pipe output to tee or file more often. We should watch out if there is any adverse effect. Change-Id: Id19e125388d55c984546e94f1a7165b03af17748 Signed-off-by: Patrick Lu <patrick.lu@intel.com>

2018-01-04jitter: change -fPIC to -fPIEPatrick Lu1-2/+2
During internal testing, we found -fPIC generated executable can cause extra jitter even on a tuned platform. After switching to -fPIE, the extra jitter went away. The exact root cause is still under investigation. Currently, the focus is on .plt related section.
