Makefile: expose target 'graph-build' to generate the build-time graphs 



Generate the build-time graphs by calling:
    make graph-build

This generates the graphs in $(O)/graphs/

It is possible to use the alternate color-scheme by setting the variable
GRAPH_ALT=1 on the command line:
    make GRAPH_ALT=1 graph-build
