[PATCH] D30339: Disable calls to fprintf when building for baremetal targets in release mode

[Ranjeet Singh via Phabricator via cfe-commits]

rs created this revision.

We've been having issues with using libcxxabi and libunwind for baremetal 
targets because fprintf is dependent on io functions, this patch disable calls 
to fprintf when building for baremetal targets in release mode.
