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 Signed-off-by: "Yann E.
