No, you build the libraries libfoo.a, libbar.a, libbaz.a, then obtain
a list of the objects that went into building them, then you dump the
objects directly into a new libcool.a.  You never run any AR unpacking
operation. That would be a tool-specific approach; there's no
guarantee that your OS actually uses AR.  Whereas building the static
libraries, then reusing the objects directly, will work on any
platform no matter the linker toolchain.

See how Chicken does it.
