Yes this should work. You can load object files from archives using
'libfoo.a:bar.o' as the file name.
I am considering adding support to search archives on the target to
complete a link.
An embedded system is typically closed so an archive that contains only
those objects you need is ideal rather than loading a complete archive
only part of is used. There is some support in the rtems-ld to create
target archives from archives used in a link. This become complicated
when you have a few modules being linked against a common set of libraries.
