You seem to be running into an *operating system kernel* limitation on the
amount of argument and environment information that can be passed from a parent
to a child. In Linux, this limit is generous; more so that on many other
operating systems, something like 128 kilobytes. On some systems it is
as low as a few kilobytes, from what I recall. Thus a build procedure
that works fine on Linux might break elsewhere.

The xargs utility can assist in breaking up large command lines.

A large archive construction job can be broken down into smaller jobs, because
you can add files to an archive; some reasonable hack using xargs to construct
the individual ar commands should do the trick.
