In general, "make build" should be *opaque*, to give a self-contained point
of entry into building the whole system.  However, I understand the need to
have some restart points[*] available when the build breaks, and I left
"do-build" as a way to redo a broken build phase:  it deliberately starts at
a reliable restart point (the former "do-lib-csu"), and continues through
building the whole tree.

I haven't removed any flexibility in building, per se.  You can still do all
those phases individually--simply cd to the appropriate directory and "make
dependall && make install".  My intent in src/Makefile was to reduce the
complexity, particularly for people who aren't well ingrained into the build
magic and don't have the time to understand it all.

[*] It's possible that a variable such as ${RESTARTAT} could be used in
    src/Makefile, to indicate a point in "make build" where real actions
    should begin.  This would allow "make build" to become fully opaque,
    without causing problems of complexity.  Would this be an amenable
    alternative?
