... until it's done.

There may be no magic solution for arbitrary packages, but
what could be done is to write some tool that "records"
the make output beforehand together with some sort of
timestamps to get a reference, which could be used (by the
same tool) to calculate time estimates during later builds.

Of course the make output (and the time used) depends on
the environment (platform, compiler, options and whatnot),
so this is not exact science, but there is room for
improvement (i.e. (mis)using the toolchain wrappers for
measuring/comparing process times instead). Still, that
tool would have to be intelligent enough to handle
differences caused by conditional compilation and the
like.

If you want a simpler, but *really* imprecise solution
you could even have someone pipe the build output through
"wc -c" and use the result together with progress(1) for
your own build...
