build in colors: Install outputs in blue/yellow [basic ics version]

"target prefix:" in yellow
"Install: file" in cyan

should be in a single command line else there are sync problems
in multithread (-j X)

These colors can be tuned in core/Makefile if you use a white terminal.
can be disabled with "export BUILD_WITH_COLORS=0"

Only the most important output is colored to reduce ics merge problems
