add DEVELOPER makefile knob to check for acknowledged warningsls/makefile-cflags-developer-tweak
We assume Git developers have a reasonably modern compiler and recommend
them to enable the DEVELOPER makefile knob to ensure their patches are
clear of all compiler warnings the Git core project cares about.
Enable the DEVELOPER makefile knob in the Travis-CI build.
