That's pretty much it. There's also the documentation build, the debug

I doubt it could be done in <10 lines of shell scripting because just
enumerating the modules would fill those. But if you feel strongly about
this definitely do it - if you come with something better we'd be glad
to replace things.
Why enumerate them? * will do, if there are files you don't want
including they shouldn't be in the directory. All the platform specific
stuff is separated in its own folders too, so that's not an issue.
It's better to have control on the actual names on the files, otherwise
what is built depends on what the builder has in that directory.
Nevertheless, there's other stuff that takes 10 lines. Consider:
# Set CFLAGS
ifeq ($(CC),cc)
CFLAGS += -m$(MODEL)
ifeq ($(BUILD),debug)
CFLAGS += -g
else
CFLAGS += -O3
endif
endif
That's 10 lines. You may be able to reduce this but not dramatically.
Overall I think you're mis-estimating what it would take to do the build
in a shell script; in all likelihood the size of the script would be
comparable to that of the makefile. I think you'd gain a much better
appreciation of what's going on if you set out to write those 10 lines.
If it does more than that then I'd be happy to look into writing the
equivalent with redo (maybe even look at porting it to D so the build
script can be written in idiomatic D). Of course if I did port it it'd
have to be LGPL, writing from scratch could be any license. The minimal
version that rebuilds everything each time is public domain.
Probably the basic redo script would give us a good idea of how things
would be.
A redo script could be the way to go if phobos was being built
incrementally, but it seems like overkill given that most of the build
is one command.
Documentation is built incrementally and unittests are executed
incrementally (successful ones are not re-run). Also, the C zip library
is built incrementally.
