Note this is not really a problem with GNU make.  You'll probably have
better support on a list more targeted at compilers or binutils.

However, on most systems ar cannot take an already-existing archive as
one of the "objects", and extract all its objects and install them into
a new archive.  That's simply a supported functionality: you can't do
it.


In your case the solution is actually pretty simple: just copy the old
library to the new library, then use ar to add in the new objects:

        cp oldlib.a libnew.a && ar rs libnew.a a.o b.o
