The documentation does not appear to specify the format of the file, nor what
happens to symbols that are not in the file, or symbols that are in the file
but which do not appear in any of the input files. (Or what happens to weak
symbols, or aliases or ...) Basically it does not appear to be very well
documented.

There is none. But ... you can use linker scripts to achieve a similar effect
- at least on an object file basis, rather than a symbol basis. In linker
scripts you can specify the order in which input sections will appear in the
output section, so you can choose for example to have .text from foo.o appear
first, followed by .text from bar.o, followed by any remaining .text sections
from any remaining input files.
Other than that though you are right, ld does not have this facility. Of
course if someone wants to write a patch to implement it, I will be happy to
review it...
