Makefile: add -ffat-lto-objects to CFLAGS
This command line option causes .o files to include additional
information and seems to be triggering a more thorough code analysis.
In particular, the uninitalized variable use cases previously missed
trigger compilation warnings when this option is enabled.
Generated code size for the Cr50 target does not change.
BRANCH=cr50, cr50-mp
